摘要
The effect of CeO2 on the properties of the Pd/Co3O4-CeO2/cordierite catalyst is a function of the method of its preparation. The catalyst obtained by the simultaneous deposition of cerium oxide and cobalt oxide showed high activity in the oxidation of CO (CO + O-2, CO + NO) and extensive oxidation of hexane (C6H14 + O-2). This behavior is due to the increased mobility of surface oxygen and increased dispersion of the catalyst components.
