A dual-functional Pd/CuO-CeO2-Y2O3 (Pd/CCY) using CuO-CeO2 as precursor was prepared and tested for catalytic combustion of toluene and ethyl acetate. It was found that the catalyst is much higher active and thermally stable for combustion of both toluene and ethyl acetate, compared with the catalyst prepared with the conventional method. Therefore, the formation of the CuO-CeO2 solid solution before coating is the key to high activity and thermal stability. Moreover, Pd/PdO species are the active phase for oxidation of toluene, while CuO or CuO-CeO2 is responsible for oxidation of ethyl acetate, and the formation of the Pd probably impels the enhancement of activity for the catalyst calcined at 1000 ℃.
