摘　　要：本实验成功合成了粒径均一的铜纳米粒子,并制备含不同粒径CuO的K_2O/CuO/SiO_2催化剂。通过对催化剂结构特点表征,及催化剂在丙烯环氧化反应中的催化性能的考察,确定了CuO粒径与催化剂催化性能的关系。The copper nanopartieles with homogeneous size were successfully synthesized and the K2O/CuO/SiO2 catalysts with different size CuO were prepared. The relationship between the particle size of CuO and the catalytic performance of the catalyst was determined through the characterization of the catalyst structure and the catalytic performance of the catalyst in the epoxidation ofpropylene.
