Abstract

A novel method for incorporation of palladium nanoparticles into a porous hypercrosslinked polystyrene matrix has been developed. The composite obtained by reduction of [Pd(π-allyl)Cl]₂ with hydrogen in supercritical CO₂ shows high catalytic activity in the hydrogenation of benzene and can be used twelve (12) times in a row without any decrease in conversion rate. The catalyst is also suitable for quantitative hydrogenation of toluene, tetralin and phenol. The obtained catalytic system is compared with the palladium composite synthesized by a conventional method based on hypercrosslinked polystyrene.

超交联聚苯乙烯中的钯纳米粒子：合成及其在芳烃加氢中的应用

摘要

已经开发了一种将钯纳米粒子掺入到多孔超交联聚苯乙烯基体中的新方法。通过还原[钯（π烯丙基）CL]的获得的复合₂与氢在超临界CO ₂示出了高的催化活性在苯的氢化，并且可以使用十二（12）次连续而不在转化率的任何降低。该催化剂也适用于甲苯，四氢萘和苯酚的定量加氢。将获得的催化体系与通过基于超交联聚苯乙烯的常规方法合成的钯复合材料进行比较。
