The present invention relates to a high surface area tungsten carbide catalyst and a method for manufacturing the same, and more particularly, it has high electrochemical activity and excellent endothelial toxicity to carbon monoxide, and thus it is possible to maintain high activity even when used for a long time in an electrode of a fuel cell. The present invention relates to a high surface area tungsten carbide catalyst and a method for preparing the same, which can obtain higher catalytic activity even with a smaller amount of the metal active component than the catalyst.

A fuel cell is a battery that electrochemically reacts fuel (hydrogen, natural gas, methanol, coal, petroleum, biomass gas, landfill gas, etc.) with an oxidant (oxygen, air) and converts the reaction energy directly into electricity. Since the aerospace program was developed in the United States, research has been actively conducted in various countries around the world for various applications such as power generation, household, transportation, and mobile power. Since the fuel cell can obtain a high energy efficiency of 90%, it is the biggest feature that the energy efficiency can be remarkably high compared to the conventional power generation technology, and is a pollution-free power generation device that does not emit NO _x and SO _x .

In the fuel cell, hydrogen or fuel is supplied to the anode electrode, oxygen is supplied to the cathode electrode, and electricity is generated by an electrochemical reaction between the anode electrode and the cathode electrode. Oxidation reaction of hydrogen or organic raw materials occurs at the anode, and reduction reaction of oxygen occurs at the cathode to generate a voltage difference between the two electrodes.

A fuel cell is classified into a phosphoric acid fuel cell, a molten carbonate fuel cell, a solid oxide fuel cell, a polymer electrolyte type or an alkaline fuel cell according to the type of electrolyte used. Each of these fuel cells operates on essentially the same principle, but differs in the type of fuel used, operating temperature, catalyst, and electrolyte.

Direct methanol fuel cell (DMFC), which has been developed recently, has high energy density, low operating temperature, and easy handling of liquid methanol fuel, which is mainly used as a mobile power source for small communication devices or computers. It is expected to be used. In addition, polymer electrolyte membrane fuel cells (PEMFCs) have superior output characteristics compared to other fuel cells, have a low operating temperature, fast start-up and response characteristics, as well as mobile power sources such as automobiles, homes, Applications include a wide range of applications such as distributed power supplies for public buildings and small power supplies for electronic devices.

Cathode and anode electrodes used in fuel cells are generally prepared by supporting a catalytic metal composed of a platinum (Pt) or a platinum-ruthenium (Pt-Ru) alloy or an alloy of various other active metals on a carbon carrier. In particular, these electrodes are expensive because they use noble metal catalysts, and have the disadvantage of lowering efficiency due to poisoning by catalyst poisons such as carbon monoxide.

Unlike other parts of the fuel cell, electrodes use precious metal catalysts, so even if they are produced in large quantities, there is little room for them to be cheap. How to maximize this is required.

Tungsten carbide has been studied to be used as an electrocatalyst because it has stability against anodic potential and endothelial toxicity against carbon monoxide in acid solution. However, tungsten carbide alone showed very low electrocatalytic activity despite high endothelial toxicity to carbon monoxide.

Various methods for synthesizing tungsten carbide for use as electrode catalysts are known, but there is no known method for preparing electrode catalysts having a high surface area or supporting other metal active ingredients thereon.

The first technical problem to be achieved by the present invention is to provide a high surface area tungsten carbide catalyst capable of dispersing the metal active ingredient well with excellent electrochemical activity and endothelial toxicity to carbon monoxide.

The second technical problem to be achieved by the present invention is to provide a method for producing the high surface area tungsten carbide catalyst.

The third technical problem to be achieved by the present invention is to provide an electrode for a fuel cell comprising the high surface area tungsten carbide.

The fourth technical problem to be achieved by the present invention is to provide a fuel cell comprising the high surface area tungsten carbide.

The present invention provides a high surface area tungsten carbide catalyst containing tungsten carbide crystal grains and having a surface area of 100 m ² / g to 500 m ² / g or more in order to achieve the first technical problem.

The present invention to achieve the second technical problem,

(a) dissolving and mixing a polymerizable monomer and a tungsten precursor in a solvent;

(b) preparing a tungsten-polymer composite comprising a polymer produced by polymerizing the monomer and a tungsten precursor;

(C) it provides a method for producing a high surface area tungsten carbide catalyst comprising the step of separating and firing the tungsten-polymer composite.

The present invention provides a fuel cell electrode comprising the high surface area tungsten carbide catalyst in order to achieve the third technical problem.

The present invention, the cathode comprising a catalyst layer and a diffusion layer to achieve the fourth technical problem; An anode comprising a catalyst layer and a diffusion layer; And an electrolyte membrane positioned between the cathode and the anode, wherein at least one of the cathode and the anode comprises the high surface area tungsten carbide catalyst.

Hereinafter, the present invention will be described in more detail.

A first aspect of the invention provides a high surface area tungsten carbide catalyst comprising tungsten carbide crystal grains and having a surface area of 100 m ² / g to 500 m ² / g. The high surface area tungsten carbide catalyst may be used as a catalyst component in an electrode of a fuel cell. In addition, the high surface area tungsten carbide catalyst may also serve as a carrier for the metal active component by supporting other metal active components on its surface.

The high surface area tungsten carbide catalyst of the present invention is formed by the aggregation of fine tungsten carbide crystal grains, and the tungsten carbide crystal grains form a single phase in WC, W ₂ C, or WC _1-x or a mixed phase thereof (where x is 0). Any real number between 1 and 1, depending on manufacturing conditions). In addition, the high surface area tungsten carbide catalyst may further include tungsten particles having a chemical formula of WO ₃ . This is formed by the reaction of tungsten atoms located on the surface of the high surface area tungsten carbide catalyst with oxygen in the air. Therefore, tungsten particles having the chemical formula of WO ₃ are mainly distributed on the surface.

Therefore, in the total high surface area tungsten carbide catalyst, the atomic ratio of tungsten, carbon and oxygen is preferably 1: m: n and 0.5 ≦ m ≦ 5 and 0 ≦ n ≦ 3. If the value of m is less than 0.5, tungsten may be present on the metal that is not bonded with carbon. If the value of m is greater than 5, free carbon is not present and the activity is low. In addition, when the value of n is larger than 3, oxygen does not stay on the surface and is incorporated into the main body, which also lowers the activity. When the value of n is 0, it means that oxygen is not bonded.

The tungsten carbide crystal particles may be tungsten carbide catalyst particles by being connected to each other by carbon. As described above, the aspect in which carbon connects tungsten carbide crystal grains may be understood, for example, in which a tungsten carbide crystal grain is embedded in a template made of carbon to form tungsten carbide catalyst particles.

The tungsten carbide catalyst has an average particle diameter of 0.01 μm to 100 μm, preferably 0.05 μm to 50 μm. If the average particle diameter is smaller than 0.01 μm, particles tend to aggregate easily, and thus are not preferable as catalyst particles. If the average particle diameter is larger than 100 μm, the specific surface area is small, which lowers the catalytic activity.

In addition, the tungsten carbide catalyst preferably has a surface area of 100 to 500 m ² / g. If the surface area is less than 100 m ² / g, the activity as a catalyst is too small is not preferred, if the surface area is larger than 500 m ² / g there is a disadvantage that the mechanical strength of the particles may be insufficient and difficult to manufacture.

As mentioned above, the high surface area tungsten carbide catalyst of the present invention may serve as a carrier for the metal active component by supporting other metal active components on its surface. Even at this time, the high surface area tungsten carbide catalyst maintains its activity as a catalyst and exhibits further improved catalytic activity as a whole with the metal active component supported on the surface.

The said metal active component is not specifically limited, What is necessary is just a metal which can act as a catalyst with respect to the redox reaction of the electrode for fuel cells. Non-limiting examples of such metals include platinum (Pt), ruthenium (Ru), osmium (Os), cobalt (Co), palladium (Pd), gallium (Ga), titanium (Ti), vanadium (V), Chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), aluminum (Al) and the like. Also included here are those in which two or more metal elements are arbitrarily selected to form an alloy.

The second aspect of the present invention provides a method for producing the high surface area tungsten carbide catalyst. Hereinafter, the manufacturing method of the said high surface area tungsten carbide catalyst is demonstrated.

The present invention comprises the steps of (a) dissolving a polymerizable monomer and a tungsten precursor in a solvent to mix;

(b) preparing a tungsten-polymer composite comprising a polymer produced by polymerizing the monomer and a tungsten precursor;

(C) it provides a method for producing a high surface area tungsten carbide catalyst comprising the step of separating and firing the tungsten-polymer composite.

First, the tungsten precursor may be a compound containing tungsten atoms and capable of supplying tungsten atoms by firing, and is not particularly limited. In particular, the tungsten precursor is preferably tungstate. The tungstate salt is preferable because the tungsten atom can be smoothly supplied even without excessively harsh conditions. More specific examples of the tungstate salts include, but are not limited to, ammonium meta tungstate (AMT), ammonium tungstate, sodium tungstate, tungsten chloride, or mixtures thereof. In particular, ammonium meta tungstate has an advantage of easily forming a tungsten-polymer composite together with a polymer described below even at a temperature close to room temperature.

The monomer which can be polymerized into a polymer may be any monomer that can be polymerized in an appropriate temperature range, and is not particularly limited. The monomer may be, for example, resorcinol / formaldehyde; Phenol / formaldehyde, pyrrole, thiophene, acronate, vinyl chloride, and the like, but are not limited thereto. The polymerization may be radical polymerization initiated by an initiator, light or heat, may be ionic polymerization, or is not particularly limited. When using resorcinol and formaldehyde as the monomer, they form a copolymer through a dehydration condensation reaction.

It is preferable that the said solvent is a polar solvent, For example, although a water or alcohol solvent is preferable, it is not limited to this. As said alcohol solvent, propanol, such as methanol, ethanol, isopropyl alcohol, butanol, pentanol, etc. are mentioned, for example. It is particularly preferred that the water is deionized water.

The relative content of the tungsten precursor and the monomer is preferably 1: 5 to 1: 200 based on the number of moles. If the content of the monomer is less than the above range, the content of free carbon is excessive, and if the content of the monomer is too much above the range, carbon-deficient tungsten carbide is produced, which is not preferable.

In addition, the relative content of the tungsten precursor and the solvent is preferably 1: 500 to 1: 3000 based on the number of moles. If the content of the solvent is less than the above range, the mixing of the reactants is difficult. If the content of the solvent is too much above the above range, the concentration of the reactant is too low, and the reaction is difficult to proceed smoothly.

The tungsten precursor, monomer and solvent may be mixed at one time, but it is preferable for uniform mixing to dissolve or disperse the solid tungsten precursor in a solvent and then mix it with the liquid monomer.

After mixing the reactants as above, the mixture is reacted. Initiation of the reaction may be by an initiator as described above, by heat or light, and is not particularly limited. The temperature of the reactant is preferably 20 ° C. to 200 ° C. or less, and the reaction time is preferably 5 hours to 48 hours.

It is preferable that the said polymerization temperature is 20 degreeC-200 degreeC. When the polymerization temperature is lower than 20 ℃, the reaction rate is too slow to take a lot of time to manufacture, when the polymerization temperature exceeds 200 ℃ difficult to control the reaction rate is difficult to produce a uniform phase.

If the reaction time is less than 5 hours, the polymerization of the polymer is not sufficient, and it is not preferable because the complex of the polymerized polymer and the tungsten precursor is not sufficiently formed. If the reaction time is longer than 48 hours, the effect of the reaction is saturated, which is uneconomical. .

When the polymerization is carried out as described above, the polymer produced as the monomer is polymerized has a gel phase in the solvent, and the tungsten precursor is contained therein, thereby sinking into precipitation.

The precipitate produced as described above is separated by a method such as filtration and calcined in an inert atmosphere. The firing is performed in a heating apparatus having a heating space, such as an oven or a heating furnace. The firing temperature is preferably carried out at 600 ℃ to 1200 ℃. If the firing temperature is lower than 600 ℃ no tungsten carbide is produced, if the firing temperature is higher than 1200 ℃ there is a disadvantage that the surface area of the produced tungsten carbide is reduced by the sintering phenomenon.

By firing as described above, a high surface area tungsten carbide catalyst can be obtained.

As described above, the high surface area tungsten carbide catalyst of the present invention may also serve as a carrier for the metal active component by supporting other metal active components on its surface. The method of supporting the metal active component on the high surface area tungsten carbide catalyst of the present invention is not particularly limited, and may be a conventional method of supporting a noble metal catalyst on a general catalyst carrier, for example, silica (SiO ₂ ). .

A third aspect of the present invention provides an electrode for a fuel cell comprising the high surface area tungsten carbide catalyst.

The method for producing the electrode may be a conventional method known as a method for producing a fuel cell electrode, and is not particularly limited. Looking at one non-limiting embodiment of the manufacturing method in detail as follows.

The binder may be a polyvinyl alcohol, polyacrylonitrile, phenol resin, polytetrafluoroethylene (PTFE), polyvinylidene fluoride, polyvinylidene fluoride-hexafluoropropylene copolymer (PVdF-HFP), Materials such as cellulose acetate can be used, and solvents include water, alcohols (methanol, ethanol, isopropyl alcohol, n-propyl alcohol, butyl alcohol), dimethylacetamide (DMAc), dimethylformamide, and dimethyl sulfoxide (DMSO). ), N-methylpyrrolidone, tetrahydrofuran and the like can be used. The slurry prepared as described above is coated on an electrode substrate and dried. The coating method may be a screen printing method, a spray coating method, a coating method using a doctor blade, a gravure coating method, a dip coating method, a silk screen method, a painting method, etc., depending on the viscosity of the composition, but is not limited thereto.

The electrode substrate may be, for example, carbon paper, more preferably a water repellent treated carbon paper, even more preferably a water repellent treated carbon paper or carbon cloth coated with a water repellent treated carbon black layer. It is not limited to. The electrode substrate serves to support the fuel cell electrode and serves as a gas diffusion layer in which the reaction gas is easily accessible to the catalyst layer by diffusing the reaction gas into the catalyst layer.

The electrode may further include a microporous layer to further enhance the gas diffusion effect between the gas diffusion layer and the catalyst layer. The microporous layer may be formed by applying, for example, a conductive material such as carbon powder, carbon black, activated carbon, acetylene black, a binder such as PTFE, and a composition containing an ionomer as necessary, but is not limited thereto. It is not.

A fourth aspect of the present invention provides a fuel cell comprising the high surface area tungsten carbide catalyst. That is, a cathode including a catalyst layer and a diffusion layer; An anode comprising a catalyst layer and a diffusion layer; And an electrolyte membrane positioned between the cathode and the anode, wherein at least one of the cathode and the anode comprises a high surface area tungsten carbide catalyst according to any one of claims 1 to 6. A fuel cell is provided.

The fuel cell of the present invention can be applied to, for example, PAFC, PEMFC, DMFC, and the like, and particularly, can be applied to DMFC more advantageously. In the production of such a fuel cell, since a conventional method known in various documents can be used, detailed description thereof is omitted here.

Hereinafter, the structure and effects of the present invention will be described in more detail with specific examples and comparative examples, but these examples are only intended to more clearly understand the present invention and are not intended to limit the scope of the present invention.

The mixture stirred as described above was placed in a container and allowed to react for 24 hours while maintaining 94 ° C. The steam generated at this time was condensed with a condenser and returned to the vessel.

After 24 hours, a tungsten precursor-polymer complex in a gel precipitated at the bottom of the vessel. The precipitate was filtered and calcined at 900 ° C. for 3 hours in an argon atmosphere.

As a result of observing the particles of the tungsten carbide catalyst prepared as described above using a scanning electron microscope (SEM), it can be seen that spherical particles of 2 μm to 4 μm are formed in a relatively uniform shape as shown in FIGS. 1A and 1B. Able to know.

In addition, XRD analysis of the spherical tungsten carbide catalyst prepared as described above showed that the tungsten carbide catalyst of the present invention was composed of WC, W ₂ C and WC _1-x phases (see FIG. 6). ). In addition, as a result of applying the Debye-Scherrer equation, it was found that the average particle diameter of the tungsten carbide crystal particles forming the spherical tungsten carbide catalyst was 14 nm.

Then, the results of the EDX analysis as also with respect to a spherical tungsten carbide catalyst prepared as described above in Fig. 2 it can be seen that the tungsten carbide catalyst of the present invention consists of tungsten, carbon and oxygen, an atomic ratio of WC _2.7 O It was found to have a composition of _1.2 .

As a result of performing a high magnification transmission microscope (HRTEM) analysis for a more accurate analysis, it can be seen that tungsten carbide crystal particles and carbon of about 15 nm form a porous sphere on a spherical tungsten carbide catalyst (see FIG. 3). This shows that carbon serves as a template for spherical spheres, linking tungsten carbide crystal grains together.

Nitrogen adsorption was calculated using the BET adsorption formula to measure the surface area. The result was 176 m ² / g.

To determine the endothelial toxicity of carbon monoxide, the maximum amount of carbon monoxide was measured. As a measurement method, a temperature desorption method (TPD) was used, and a value of the carbon monoxide peak was calculated. The measured carbon monoxide deposit was 956 μmol / g, corresponding to 33% of the total available surface, and 3.3 × 10 ¹⁴ cm ⁻² in terms of adsorption point concentration (water density). In view of the deposition amount and surface area, this is an extremely high value compared to the values previously reported (137 μmol / g, 55 m ² / g).

Comparative Example 1

Spherical carbon was synthesized in the same manner as in Example 1 except that no ammonium meta tungstate was added. The surface area of the synthesized spherical carbon was measured in the same manner as in Example 1, and the result was 635 m ² / g. Carbon monoxide adsorption experiment using the spherical carbon was confirmed that the carbon monoxide does not chemisorption.

Comparative Example 2

Carbon monoxide adsorption experiments using commercially available tungsten carbide (manufactured by Alfa-JM Co., Ltd.) confirmed that carbon monoxide could not be chemisorbed.

<Example 2>

After dissolving 0.29 g of NaOH in 25 ml of distilled water, 0.64 g of NaBH ₄ was dissolved, and 0.6 g of the spherical tungsten carbide catalyst prepared in Example 1 was added to the solution and stirred to disperse well. Then, ₂ ml of H ₂ PtCl _{6 was} added to the solution, followed by additional stirring for 30 minutes, to thereby prepare 15% Pt / tungsten carbide catalyst by centrifugation and drying. A high magnification transmission micrograph of the prepared catalyst is shown in FIG. 4A.

<Example 3>

A catalyst was prepared in the same manner as in Example 2, except that 1 ml of H ₂ PtCl ₆ was added instead of 2 ml.

Comparative Example 3

After dissolving 0.2 g of NaOH in 25 ml of distilled water, 0.64 g of NaBH ₄ was dissolved, and 0.3 g of spherical carbon prepared in Comparative Example 1 was added to the solution, followed by stirring to disperse well. Then, 1 ml of H ₂ PtCl ₆ and 0.4 g of RuCl ₃ were added to the solution, followed by additional stirring for 30 minutes to prepare 11% Pt-9% Ru / spherical carbon catalyst by centrifugation and drying. High magnification transmission micrographs of the catalyst are shown in FIG. 4B.

<Comparative Example 4>

A commercial catalyst consisting of 20% Pt-Ru / carbon black (Vulcan-XC 72R) catalyst (manufactured by E-TEK) was used.

The catalysts prepared in Examples 2 and 3 and Comparative Examples 3 and 4 were applied to the electrochemical oxidation of methanol. First, the electrochemical surface area (ESA) of various catalysts was measured using cyclic voltammetry using the hydrogen adsorption and desorption method. In addition, their inertness and mass activity at 0.75 V were measured. The measurement results are summarized in Table 1 below.

TABLE 1

Precious metal Electrochemical surface area, ESA (m ² / g) Inactive at 0.75 V (mA / cm ² ) Mass activity (at 0.75 V) (mA / mg Pt) Example 2 15% Pt 327 156 728 Example 3 7.5% Pt 189 224 560 Comparative Example 3 11% Pt / 9% Ru 58 87 280 Comparative Example 4 20% Pt-Ru 71 114 307

As can be seen in Table 1, it can be seen that the electrochemical surface area values of Examples 2 and 3 are 2 to 5 times higher than those of the comparative example. In addition, it can be seen that even in the inactive and specific surface areas, in the case of the examples, it contained significantly less than the value of the comparative example even if it contained a smaller amount of the noble metal catalyst. This indicates that the platinum particles are best dispersed when supported on tungsten carbide, and thus the utilization of platinum is maximized when supported on the high surface area tungsten carbide catalyst of the present invention.

The platinum / high surface area tungsten carbide catalysts of Examples 2 and 3, despite the absence of ruthenium, reduced carbon monoxide poisoning and increased the activity of methanol for electrical oxidation. This is believed to be due to the high surface area tungsten carbide catalyst directly participating in the decomposition reaction of methanol, activating water to generate a hydroxyl group (-OH), thereby removing carbon monoxide, which is a catalyst poison.

<Example 4>

The platinum / high surface area tungsten carbide catalyst prepared in Example 2 was continuously subjected to methanol oxidation in a 1 M sulfuric acid-1 M methanol solution. As shown in FIG. 5, after 30 iterations, the area of the cyclic voltametry was stabilized and hardly changed. Thus, it was found that the catalyst is stable during the electrode reaction.

Although described in detail with respect to preferred embodiments of the present invention as described above, those of ordinary skill in the art, without departing from the spirit and scope of the invention as defined in the appended claims Various modifications may be made to the invention. Therefore, changes in the future embodiments of the present invention will not be able to escape the technology of the present invention.

The high surface area tungsten carbide catalyst or the catalyst having a metal active component loaded on the high surface area tungsten carbide catalyst has high electrochemical activity and endothelial toxicity to carbon monoxide, and thus can maintain high activity even when used for a long time in an electrode of a fuel cell. In addition, since the surface area is large and the metal active components can be dispersed well, higher catalytic activity can be obtained even using a smaller amount of metal active components than conventional noble metal catalysts. It is effective to make it cheaper.
