摘要

以氨基功能化的聚离子液体为载体，通过离子交换和水热还原，制备出负载型催化剂PVAD/MoO

/Ag，考察了其催化苯乙烯氧化的性能。采用FT-IR、TG、XRD、SEM和BET对其所制备的催化剂进行表征。苯乙烯氧化性能研究结果表明，PVAD/MoO

/Ag

表现出最佳的催化活性，在乙腈为溶剂，温度为90℃，氧气压力为0.8 MPa的条件下，反应8 h，苯乙烯的转化率为49.9%，苯甲醛的选择性达到74.4%。并且催化剂重复使用5次，活性没有明显下降，表现出良好的重复利用性。

Abstract

The supported catalyst PVAD/MoO

/Ag was prepared by ion exchange and hydrothermal reduction using amino-functionalized polyionic liquid as the carrier

and its performance in catalyzing the oxidation of styrene was investigated. The prepared catalysts were characterized by FT-IR

XRD

SEM and BET. The results showed that PVAD/MoO

/Ag

showed the best catalytic activity.

Under the conditions of acetonitrile as solvent

temperature of 90℃ and oxygen pressure of 0.8 MPa for 8 h

the conversion rate of styrene was 49.9%

and the selectivity of benzaldehyde reached 74.4%. Moreover

the activity did not decrease significantly after reused 5 times

showing good reusability.
