多金属氧酸盐光催化降解有机污染物研究进展

Progress in Photocatalytic Degradation of Organic Pollutants by Polyoxometalates

光催化作为一种高级氧化技术在有机污染物的降解方面得到广泛研究。本文概述了多金属氧酸盐光催化降解有机卤化物、染料、农药等有机污染物的研究进展,介绍了多金属氧酸盐与半导体氧化物、层状双氢氧化物、分子筛与介孔材料、离子交换树脂形成的复合材料,以及与半导体氧化物、聚乙烯醇等形成的复合膜材料的相关研究。

Photocatalysis has been widely studied as an advanced oxidation process in degradation of organic pollutants.In this paper,homogeneous photocatalytic degradation of persistent organic pollutants including organic halides,dyes,pesticides,etc.by polyoxometalates were introduced.Furthermore,researches of composite materials combined polyoxometalates with semiconductor oxides,layered double hydroxides,molecular sieves and mesoporous materials,anionic exchange resin,or composite films combined polyoxometalates with semiconductor oxides or polyvinyl alcohol were reviewed.
