摘要：

Ce0.7M0.3CoOx catalysts were prepared by polyatomic alcohol method. The crystal structure, reduction and adsorption properties, and specific surface were investigated by XRD, TPR, TPD, BET, respectively. The results show that catalysts doped with different oxides can make great effects on the catalytic properties of the Co3O4-CeO2. The interaction between doping oxides (SrO, NiO, La2O3, ZrO2, Nd2O3) and Co3O4-CeO2 is contributed to the change of the reduction and adsorption performance, and specific surface area of the catalysts. SrO doping can promote CeO2 reduction, CO adsorption and low-temperature oxidative activity of the catalysts. The conversion of CO can reach 100% over the Ce0.7Sr0.3CoOx at 120 degrees C temperature.
