铜负载量对介孔铜铈变换催化剂结构与性能的影响

he CuO/CeO2 water gas shift catalysts with different copper loadings were prepared by impregnation method. The structure and performance of the catalyst were characterized by XRD, BET and TPR, and the activities on the shift reaction were also tested. The results show that Copper loadings are an important factor to affect the structure and properties of CuO/CeO2 catalyst. The appropriate loaded amount of copper help to improve catalytic activity for water gas shift reaction, and the higher copper loading would formed crystalline phase of copper oxide which inhibited the catalytic activity of CuO/CeO2 catalyst. The best copper loadings are 12%.
