聚合物负载贵金属催化剂的合成及其在氢化反应中的应用进展

聚合物负载贵金属催化剂大多具有良好的光学催化活性,并且反应后容易从反应物中分离,重复实用性高,成为近年来人们研究的热点。常见的聚合物载体主要为有机聚合物及多种无机一有机杂化材料。本文主要按聚合物载体种类的不同,综述了聚合物负载Pt、Pd、Rh等贵金属催化剂的制备方法及其在烯烃、二烯烃、炔烃和硝基芳香化合物等物质的催化氢化中的应用情况。同时,对以树形分子为载体的催化剂、负载多元金属催化剂以及负载金型催化剂的研究及应用情况也进行了总结和评述。

Progress in Synthesis and Application on Hydrogenation Reaction of Polymer-supported Noble Metal Catalysts

Most of the polymer-supported noble metal catalysts had high optical catalytic activity.Furthermore,they were separated readily from products after reaction and could be reused several times without any remarkable loss in optical catalytic activity,which became an important researching issue.The general polymeric supports included organic polymers and inorganic-organic hybrid composites.According to the type of polymeric support,the syntheses and applications in the hydrogenation of alkylenes,dienes,alkynes and nitroaromatics,etc.,of polymer-supported noble metal catalysts as Pt,Pd and Rh were summarized in this paper.The research on dendrimer-supported catalyst,multiple-metal-loaded catalyst and nano-gold-loaded catalyst was also generalized and commented.
