摘要

利用电纺丝技术制备出苯乙烯-丙烯腈共聚物负载钯的纳米丝催化剂.对催化剂进行了SEM、TEM、IR和XPS的测试.所制备的催化剂对α-己烯催化氢化结果表明

该催化剂在常温、氢气常压下具有很高的催化活性和较好的重复使用性

并且催化氢化过程中存在烯烃的异构化反应.实验结果表明

反应时间为150 min时纳米催化剂A对α-己烯催化加氢生成正己烷的转化率是传统催化剂PdCl2/γ-Al2O3的4.7倍.

Abstract

The poly(styrene-co-acrylonitrile) supported palladium catalyst bearing a nano-fibrous morphology was prepared via electrospinning technique

and the catalyst was characterized by IR

SEM

TEM and XPS.The nano-fiber supported catalyst has high activity and good recycling property for hydrogenation of α-olefin at room temperature under 101.3 Pa.hydrogen pressure.In addition

it was found that the hydrogenation reaction of α-hexene was accompanied with the isomerization reaction.The experimental results show that the yield of the α-hexene to hexane catalyzed by the nano-fiber supported palladium catalyst was 4.7 times higher than that of PdCl2/γ-Al2O3 catalyst.The hydrogenation of α-tetradecylene

cyclohexene

nitrobenzol and styrene by the nano-fiber supported palladium catalyst was also studied

the selectivity to primary products of the hydrogenation of cyclohexene

nitrobenzol and styrene was 100%.
