Abstract
Abstract The invention relates to an active alumina catalyst with additions of CeO2, ZrO2 and Fe2O3 and/or NiO as support and an active phase, applied thereto, of platinum, palladium and/or rhodium and a base metal, which catalyst is obtainable by impregnating the support containing the additives with solutions of salts of the metals for the active phase, the base metal of the active phase being cerium, and by drying and heating to 250 to 650 DEG C. The catalyst can be used for the oxidation and/or reduction of the exhaust gases from internal combustion engines.
