| 摘 要： | Mesoporous CeO2 was first synthesized by hydrothermal method,and then used to synthesize different contents of CuO）x/CeO2（x：molar ratio of Cu to Ce） by deposition-precipitation method.These materials were characterized by X-ray diffraction（XRD）,N2 adsorption and desorption,H2 temperature programmed reduction（H2-TPR） and O2 temperature programmed desorption（O2-TPD） to study the crystal structure,surface area,and the mechanism of CO oxidation.The results show that,on XRD patterns,no evidence of CuO diffraction peaks is present until Cu loading is increased to 20%.The BET surface area decreases noticeably with the increase of Cu content.Compared with other samples,the better reducibility and activity oxygen species of（CuO）10%/CeO2coincide with its better catalytic activity.
