ABSTRACT:
The present invention broadly relates to a catalyst for promoting the oxidation-reduction reactions of the exhaust gases produced by an internal combustion engine wherein the catalyst comprises; tungsten oxide, a basic metal oxide, and a noble metal. More narrowly, the present invention relates to a catalyst for promoting oxidation-reduction reactions with the exhaust gases produced by internal combustion engine wherein the catalyst comprises; a composite oxide comprised of a refractory oxide, tungsten oxide in juxtaposed relation with the refractory oxide, and a basic metal oxide in juxtaposed relation with the tungsten oxide; and arrayed on the composite oxide a noble metal.
