磁纳米贵金属催化剂的制备及加氢性能

摘要

Noble metal catalysts for hydroganation of nitrobenzene compound were prepared using poly-ethyleneimine as the crosslinking agent, ferroferric oxide ( Fe3 O4 ) as the carrier and characterized by means of FT-IR,XRD and TEM. The results showed that the catalysts for chloronitrobenzene hydrogena-tion exhibited high conversion and good stability, and were recycled easily.%以有机分子聚乙烯亚胺为交联剂,四氧化三铁为载体,制备了贵金属催化剂用于催化硝基苯化合物加氢反应,采用FT - IR、XRD和TEM对催化剂进行表征.结果表明,制取的磁纳米贵金属催化剂催化对氯硝基苯加氢反应转化率高,稳定性较好,较容易回收.
