| 摘 要： | 通过静电纺丝和热交联技术、以聚乙烯醇( PVA)作为载体制备了一种电纺纤维膜负载型钯催化剂.利用扫描电镜(SEM)、能谱仪(EDS)和X射线光电子能谱(XPS)对其进行了表征.SEM结果显示:PdCl2的加入导致PVA纤维直径增加、形貌变差,而热交联过程可以减小纤维直径、改善纤维形貌.XPS表征则表明PVA可以还原pd...

| Abstract: | A palladium catalyst supported on poly(vinyl alcohol)(PVA)electrospun mat(Pd/PVA)was prepared by electrospinning PVA and PdCl2 mixture solution in 80 vol.%acetic acid solution and then a thermal crosslinking process.Scanning electron microscopy(SEM)showed that the crossslinking process could improve the morphology and decrease the diameter of the Pd/PVA fiber.The X-ray photoelectron spectrum demonstrated that the PVA could reduce the Pd2+ into Pd0.The cross-coupling reactions of aromatic iodides with alkene... |
