  多金属氧酸盐(polyoxometalates,POMs)的Br(?)nsted酸性和自身的氧化还原性,尤其本身强的多电子转移能力可以应用于光电材料和催化氧化领域中。在POMs催化研究领域POMs易溶于水和有机溶剂,导致催化反应难以回收,并且POMs的比表面积小,极大的限制了其在催化领域的应用。因此,如何提高POMs的循环使用性并制备长效稳定的POMs材料一直是POMs催化领域的研究热点。而开发新的固体POMs合成策略,实现POMs高效、稳定的固载是人们追求的目标。静电纺丝技术是构建一维纳米材料常用的方式,也是将POMs固载化的有效手段。本论文以静电纺丝技术为基础,围绕POMs一维纳米复合材料的合成、表征及催化氧化性能展开研究。具体内容如下:利用静电纺丝技术合成了[Al2O3/Polymethylmethacrylate]/[H5PMo10V2O40/Polymethylmethacrylate]([Al2O3/PMMA]/[HPMo...
