摘 要：CeO2-ZrO2 mixed oxide（Ce0.6Zr0.4O2） prepared by microwave-assisted heating co-precipitation was used as a support to prepare a series of CuO/Ce0.6Zr0.4O2 catalysts with various CuO contents（0 wt.%–15 wt.%） via the method of incipient-wetness impregnation.The obtained CuO/Ce0.6Zr0.4O2 samples were characterized by N2 adsorption,XRD,Raman,TEM and H2-TPR technologies,and their catalytic activities for CO oxidation were investigated.The results showed that the activity of CuO/Ce0.6Zr0.4O2 catalyst was strongly influenced by the content of CuO,and the catalyst with 10 wt.% CuO exhibited the best catalytic activity in CO oxidation,which could be attributed to the high dispersion and reducibility of CuO,and high oxygen vacancy concentration in the catalyst.
