| 摘 要： | 通过使用聚乙烯吡咯烷酮作为稳定剂，合成了磁性Pd/Fe3O4纳米颗粒催化剂。对该催化剂进行粉末X射线衍射、透射电子显微镜、感应耦合等离子体和磁性表征。将Pd/Fe3O4催化剂用于Heck反应，检测其催化性能。测试结果表明Pd纳米颗粒负载在Fe3O4纳米颗粒上，而且催化剂的尺寸<20 nm，并在Heck反应中表现了极好的催化性能。此外，催化剂可以通过磁场回收利用， 且催化活性没有显著的降低。

| Abstract: | Pd/Fe3O4 NPs have been successfully synthesized using polyvinyl pyrrolidone as a stabilizing agent. The resultant samples were characterized by X-ray diffraction, transmission electron microscopy, inductively coupled plasma, and magnetic studies. The Pd/Fe3O4 NPs catalyst was also applied in the Heck reaction to evaluate the catalytic performance. The results show that the cubic phase of Pd coexists with the cubic phase of Fe3O4, and the catalysts have size less 20 nm and the excellent catalytic activity of Pd/Fe3O4 NPs in the Heck reaction. In addition, the catalyst can be recovered via a magnet and reused several times without significant loss of its catalytic activity. |
