Abstract：The coprecipitation method was applied to prepare CeO2-MnOx composite metal oxide.The effect of CeO2-MnOx calcination temperature on CO preferential oxidation in H2-rich gases over CuO based catalyst was investigated.The samples were characterized by means of X-ray diffraction(XRD),BET surface area,H2 temperature-programmed reduction(H2-TPR),CO temperature-programmed desorption(CO-TPD) and X-ray photoelectron spectra(XPS).Results showed that the calcination temperature of CeO2-MnOx supports would have certain impact on the structural properties,redox performance and catalytical activities of CuO/CeO2-MnOx catalysts for the CO preferential oxidation in H2-rich gases.When calcined at 500℃,CuO/CeO2-MnOx catalyst exhibited the best catalytic activity and higher CO conversion in H2-rich gas,which should be related to the partly formation of CeO2-MnOx solid solution,stronger interaction between the CeO2 and MnOx,more amounts of highly dispersed CuxO and more CO adsorption amounts.
