The Dispersed States of Copper Species on CuO/ZrO_2 Catalysts and Its Influence on the Catalytic Performance

ZHOU Ren-Xian; JIANG Xiao-Yuan; LU Guang-Lie; ZHENG Xiao-Ming(Institute of Catalysis, Hangzhou University, Hangzhou,310028 )  
Copper/Zirconia catalysts were prepared by impregnation method andcharacterized by XRD, TPR and TPD-MS. It was concluded that four oxygen desorption peaks fromtwo different temperature ranges were related to oxygen species of surface adsorption,highly-dispersed copper oxide on ZrO2 and CuO phase, respectively, and the highly-dispersedcopper oxide was easily reduced, which leads to a dramatic increase in oxidation activity.
