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-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。
Most of polymer-supported noble metal catalysts have good optical catalytic activity, and are easily separated from the reactants after the reaction, resulting in high repetition and practicability, which has become a hot spot in recent years. Common polymer carriers are mainly organic polymers and a variety of inorganic - organic hybrid materials. In this paper, the preparation methods of polymer supported Pt, Pd, Rh and other noble metal catalysts and their application in the catalytic hydrogenation of olefins, diolefins, alkynes and nitroaromatics are summarized . At the same time, the research and application of dendrimer supported catalysts, supported multimetallic catalysts and supported gold catalysts are also summarized and reviewed.
