THE NATURE OF SURFACE OXYGEN SPECIES ON CuO/ZrO 2 AND ITS INFLUENCE ON OXIDATION OF CO

Zhou Renxian, Jiang Xiaoyuan, Mao Jianxin, Zheng Xiaoming (Institute of Catalysis, Hangzhou University, Hangzhou 310028)  
The thermal desorption properties of O 2 species on CuO/ZrO 2 and its influence on the catalytic performance were studied by TPD MS, TPR and TG methods. The results indicated that there were two O 2 desorption peaks, relating to surface layer CuO x and CuO phase, respectively. The surface layer CuO x is easily reduced, and leads to a dramatic increase in CO oxidation activity.
