| 摘 要： | 制备了铁磁性Fe3O4基质,并引入磷钨酸尿素复合物制备了有机硫化物氧化催化剂(HPW-Urea/Fe3O4),并通过IR、XRD、Raman和TG等技术手段测定了磁性催化剂的物理化学和热学性质。 研究结果表明,在Fe3O4上引入HPW-Urea后,磷钨酸尿素复合物以Keggin结构存在于载体Fe3O4上,且和载体之间是化学键作用。 在以有机硫化物乙硫醇的正己烷溶液的H2O2氧化反应中,磷钨酸尿素复合物的引入提高了磁性Fe3O4对乙硫醇的氧化活性,并探讨了尿素在活性改善中的作用。

| Abstract: | Oxidation catalysts of organic sulfide were synthesized by the ferromagnetic Fe3O4 matrix and phosphotungstic acid urea complexes(PAUC). The properties of products were characterized by IR, XRD, Raman and TG. With introduction of oxidation catalysts of organic sulfide, it is found that PAUC exists on Fe3O4 support in a Keggin structure and there is a chemical bond effect between them. If the H2O2 oxidation of ethanethiol proceeds in n-hexane, the oxidation activity of ethanethiol over ferromagnetic Fe3O4 matrix is increased in the presence of the PAUC. The effect of urea on activity has been discussed. |
