| 摘要: 本文研究了三核钨簇合物［W3O2(CH3CO2)6(H2O)3］Br3·2H2O与一些物质组成的二元催化剂对苯乙烯氧化反应的催化作用，结果表明：钨簇合物-V2O5催化剂对苯乙烯氧化反应的催化效果特别显著，而且在反应前后其重量、结构及催化活性基本不变，可以多次回收重复使用。对影响钨簇合物-V2O5催化剂催化性能的几个因素进行了讨论，测定了催化剂及其吸附氧气的红外光谱，说明钨簇合物及V2O5可以与O2形成分子氧配合物及超氧(O-2)配合物。 |

| Abstract: The catalytic performance of some composite catalysts for the oxidation of styrene were studied. The results show that tungsten cluster-V2O5 composite catalyst has remarkable catalytic activity and it can be used repeatly without change in its weight, structure and activity. The factors taht influence catalytic performance of tungsten cluster-V2O5 composite catalyst were discussed. The infrared spectra were measured for catalysts and ones absorbed oxygen. The results indicate that tungsten cluster and V2O5 can form molecular oxygen (O2) complexes and superoxide ion (O-2) complexes with oxygen. |
