Abstract:

As a kind of mild green photocatalysts, polyoxometalates have a good prospect in photocatalysis due to its high activity, good selectivity and non-toxicity. Researchers have been working on the heterogeneity of polyoxometalates-based catalysts in recent years in order to facilitate recycling. The structure and photocatalytic mechanism of polyoxomet alate are introduced. The methods for preparing heterogeneous polyoxometalates-based catalytic materials are summarized. The research progress of heterogeneous polyoxometalates catalysts in photocatalysis is also reviewed.

Key words: polyoxometalates, photocatalysis, heterogeneous phase, immobilization, solidification

摘要：

多酸作为一种温和的绿色光催化材料，因具有活性高、选择性好、无毒等优点而表现出很好的光催化应用前景。为方便回收与循环利用，近年来研究者一直致力于多酸基催化剂的异相化研究。介绍了多酸的结构和光催化作用机理，总结了制备异相多酸基催化材料的方法，并分类综述了非均相多酸催化剂在光催化领域的研究进展。
