BASE METAL AUTOMOTIVE EXHAUST CATALYSTS WITH IMPROVED ACTIVITY AND STABILITY Abstract of the Disclosure An improved particulate washcoat for use on a ceramic or metallic support is disclosed for the treatment of automotive exhaust gases. The mixture consists essentially of high surface area ceria particles and alumina particles wherein the ceria particles bear copper oxide. Preferably, one of chromium oxide, manganese oxide and tin oxide are dispersed over both the ceria and alumina particles of the washcoat. |
