Abstract

La présente invention concerne un matériau conducteur d'ion oxygène (OIC)/de stockage d'oxygène (OS), plus particulièrement un OIC/OS présentant une structure cristalline cubique stable, associé à une méthode permettant d'activer les propriétés catalytiques du OIC/OS grâce à l'introduction post-synthèse de métaux non précieux, par le biais d'un processus d'échange basique (alcalin). L'invention concerne également l'application desdits matériaux pour contrôler des émissions de gaz d'échappement de véhicules.
