| 摘 要： | 利用静电纺丝和交联技术,制备了植酸(PA)修饰聚乙烯醇(PVA)纤维膜负载钯催化剂.利用扫描电子显微镜(SEM)表征了纤维膜的微观结构;采用扫描电子显微镜-能谱仪(SEM-EDS)分析了Pd催化中心在纤维膜上的分布;采用红外光谱研究了纤维膜的化学结构.Mizoroki-Heck偶联反应结果显示,植酸的引入可以提高纤维膜催化剂的催化活性;该催化剂对不同结构的碘代芳烃和丙烯酸酯都表现出良好的催化性能;而且该催化剂至少可以重复使用4次其活性基本保持不变. |

| Abstract: | Phytic acid modified poly(vinyl alcohol) fiber mat is prepared by electro spinning and used as the supporting materials of palladium catalyst. The fiber morphologies are recorded by scanning electron microscopy (SEM) and the dispersion of palladium particles is analyzed by SEM- Energy Dispersive Spectrometer (SEM-EDS). FT-IR spectra are used to characterize the chemical structure of the fiber mat. The catalytic performance of this novel catalyst is evaluated by Mizoroki-Heck reactions. The results show that this catalyst is very efficient for the Mizoroki-Heck reaction of aromatic iodides with yields being over 85%. Moreover, the catalyst could be used four times with only little loss of catalytic activity. |
| Keywords: | palladium catalyst supported catalyst Mizoroki-Heck reaction electro spinning phytic acid |
