Zusammenfassung:A catalyst is provided with is suitable for catalysing the oxidation of carbon monoxide and hydrocarbons and reducing hazardous nitrous oxides. The catalyst comprises an oxide support selected from zirconium oxide, cerium oxide and mixtures thereof having captured thereon a noble metal in catalytically effective form and preferably also a transition metal oxide. The preferred catalyst has gold as the noble metal and cobalt oxide, having a spinel structure, as the transition metal oxide. The gold in such catalyst is associated with the cobalt oxide.
