以六亚甲基四胺为还原剂,聚乙烯吡咯烷酮为保护剂,通过化学还原方法合成银纳米溶胶后负载到活性炭上制备Ag/C催化剂.探讨了催化剂制备条件和形成过程,通过XRD、SEM、TEM等表征手段分析了催化剂的组成和结构,在无溶剂条件下,氧气为氧化剂,采用Ag/C催化剂催化环己烯氧化反应,研究催化剂结构与催化性能之间的关系,实现了环己烯的绿色催化氧化. Ag / C catalyst was prepared by the reaction of hexamethylenetetramine and polyvinylpyrrolidone as protective agent, and the silver nano-sol was synthesized by chemical reduction and then loaded onto activated carbon. The preparation conditions and the formation process of the catalyst were discussed. , TEM and other characterization methods to analyze the composition and structure of the catalyst. Under the condition of no solvent, oxygen is used as oxidant, the oxidation of cyclohexene is catalyzed by Ag / C catalyst, the relationship between the structure of catalyst and the catalytic performance is studied, The green catalytic oxidation of olefins.
