A catalyst for accelerating the oxidation of a gaseous compound by an oxygen ion supplied via a solid electrolyte in a circumstance free of an oxygen molecule, characterized in that it comprises metal oxide particles which are formed by providing a mixed solution containing two types of metal salts having different metals dissolved therein, subjecting the mixed solution to coprecipitation to prepare a precipitate having two types of metal hydrates mixed with each other, and firing the precipitate, and have a composition represented by the formula: ABO2 wherein A represents an element selected from the group consisting of Pd, Pt, Cu and Ag and B represents an element selected from the group consisting of Co, Cr, Rh, Al, Ga, Fe, In, Sc and Tl. The above catalyst is an oxidation catalyst for a gaseous compound which can be formed in the form of fine particles with no pulverizing operations and exhibits excellent catalytic activity for oxidation.

La présente invention concerne un catalyseur accélérant l'oxydation d'un composé gazeux par un ion d'oxygène fourni via un électrolyte solide en l'absence de molécule d'oxygène. Ce catalyseur est caractérisé en ce qu'il comprend des particules d'oxyde métallique que l'on obtient en prenant une solution mélangée de deux types de sels de métaux dans laquelle sont dissous différents métaux, puis en soumettant à coprécipitation la solution mélangée de façon à obtenir un précipité de deux hydrates de métaux mélangés entre eux, et enfin en calcinant ce précipité. La composition de ce catalyseur se représente par la formule ABO¿2? dans laquelle A est un élément du groupe des Pd, Pt, Cu et Ag, et B est un élément du groupe des Co, Cr, Rh, La, Ga, Fe, In, Sc et Tl. Le catalyseur de l'invention est un catalyseur d'oxydation pour un composé gazeux, qui peut être obtenu sous forme de fines particules sans opérations de pulvérisation, et fait preuve d'une excellente activité catalytique pour l'oxydation.
