The titanium-containing solution is contained in silica gel by rotating, vibrating, or shaking the container in a cylindrical container attached thereto, and then heating and calcining to obtain the target titanium oxide photocatalyst high-supporting silica gel.

述の問題は解決される。In addition, when a titanium-containing solution is included in silica gel, in a conventional method such as an impregnation method which is generally used, when a titanium-containing solution exceeding the total pore volume of the silica gel is used, the silica gel is used. Excessive titanium-containing solution covers the surface, and when heated and baked, it is not preferable because a titanium oxide film having a very small specific surface area and easily peelable is formed on the silica gel surface. Even if a titanium-containing solution exceeding the total pore volume of the silica gel is used, if the excess titanium-containing solution covering the surface of the silica gel is washed and removed using a diluent or the like, the silica gel surface can be heated and calcined. Since the titanium oxide film is not formed, the above-mentioned problem is solved.

ができる。Next, the heating and sintering of the silica gel containing the titanium-containing solution is carried out by, for example, gradually heating from room temperature to 400 to 700 in order to obtain titanium oxide having a high-performance crystal form of anatase as a photocatalyst. After holding at a final temperature of ° C. for a certain time, the reaction is cooled to room temperature. Firing temperature is 40
If the temperature is lower than 0 ° C. or higher than 700 ° C., rutile or amorphous titanium oxide mixed with low activity as a photocatalyst is not preferable. The firing furnace to be used is desirably a gas furnace having sufficient oxygen required for firing. However, an electric furnace that does not supply oxygen sufficiently can be fired without any problem if oxygen is supplied.

れらも無制限に用いることができる。When the titanium oxide photocatalyst-supported silica gel according to the present invention contains a titanium-containing solution having a volume smaller than the total pore volume of the silica gel, these liquids slowly permeate from the silica gel surface toward the center, and A hollow sphere having a volume less than the pore volume remaining as a cavity in the center of the silica gel is produced, and by heating and calcining it, a titanium oxide is obtained only in the surface layer. Even when a titanium-containing solution having a volume equal to the total pore volume of the silica gel is contained, if the concentration of the diluting liquid contained in the titanium-containing solution is 5 to 75% by weight, the dilution action is performed by the filter action of the silica gel pores. If the liquid has a low molecular weight, a solution having a gradient in which the titanium concentration is higher in the surface portion and lower in the center portion can be obtained. As a result, a titanium oxide photocatalyst-supported silica gel with a lower gradient is obtained.If a titanium-containing solution that is easily hydrolyzed is used, the silica gel with a smaller average pore diameter is more remarkable, but the silanol groups present in the silica gel By reacting titanium quickly from the surface layer, these liquids can be contained at a high concentration in the surface layer, and this is fired. High titanium oxide concentration by Rukoto as the surface layer portion, titanium oxide photocatalyst carrying silica gel are obtained having a slope that lower the heart, but they can be used also unlimited.

Silica gel can also be used without limitation. The reason why the activity increases is not clear, but the reaction between hydrogen peroxide, which is a kind of active oxygen generated when light is applied to titanium oxide, and a divalent iron ion to produce a hydroxyl radical is not described. It is also known as the Fenton reaction, and it is thought that a similar mechanism works.
