多金屬氧酸鹽(polyoxometalates,POMs)的Br(?)nsted酸性和自身的氧化還原性,尤其本身強的多電子轉(zhuǎn)移能力可以應(yīng)用于光電材料和催化氧化領(lǐng)域中。在POMs催化研究領(lǐng)域POMs易溶于水和有機溶劑,導(dǎo)致催化反應(yīng)難以回收,并且POMs的比表面積小,極大的限制了其在催化領(lǐng)域的應(yīng)用。因此,如何提高POMs的循環(huán)使用性并制備長效穩(wěn)定的POMs材料一直是POMs催化領(lǐng)域的研究熱點。而開發(fā)新的固體POMs合成策略,實現(xiàn)POMs高效、穩(wěn)定的固載是人們追求的目標(biāo)。靜電紡絲技術(shù)是構(gòu)建一維納米材料常用的方式,也是將POMs固載化的有效手段。本論文以靜電紡絲技術(shù)為基礎(chǔ),圍繞POMs一維納米復(fù)合材料的合成、表征及催化氧化性能展開研究。具體內(nèi)容如下:利用靜電紡絲技術(shù)合成了[Al2O3/Polymethylmethacrylate]/[H5PMo10V2O40/Polymethylmethacrylate]([Al2O3/PMMA]/[HPMo...
