Abstract The conventional three��way catalysts are not efficient enough to remove the CO and hydrocarbons during vehicle cold��start period due to the low temperature of catalyst bed. Recently��transition��metal oxide catalysts used for oxidation of CO and hydrocarbons at low temperature have attracted much attention. The main advances in oxidation of CO and hydrocarbons on transition metal oxide catalysts during the past several years are systematically reviewed��mainly on the Cu��Co and Mn based oxides which possess good oxidation performance. The reaction mechanism involving interface oxygen vacancy on the catalyst participated in the oxidation reaction is summarized. The research tendency of transition��metal oxide catalysts used for low��temperature oxidation of CO and hydrocarbons is proposed.
