摘　　要：制备了碳负载钯催化剂(Pd/C)以及氨基改性二氧化硅负载钯(Pd/Si O2-NH2)催化剂。两种催化剂应用于以溴苯为模型反应的Heck反应中,对比了两种催化剂的反应活性以及重复使用率。研究表明,Pd/C催化剂在Heck反应中有较高的催化活性,但是其重复使用寿命低于Pd/Si O2-NH2催化剂。In this work,we prepared the active carbon supported palladium（ Pd / C） and amino groups modified silica supported palladium Pd / SiO2- NH2 catalysts. The two catalysts were used for catalyzing the Heck reactions that modeled as bromobenzene. In the reactions,we compared the reactive activities and reuse ratio. It suggested that Pd / C catalysts have higher catalystic activities than the Pd / SiO2- NH2 catalysts. However,its reuse performances were worse than the Pd / SiO2- NH2.
