摘要
综述了杂多酸对染料废水光催化降解的负载材料,包括负载型多酸-氧化物,缺位型多酸-有机胺-氧化物,缺位型多酸-氧化物以及其它POM复合光催化剂。杂多酸与有机物反应的机理主要是电子-空穴对的产生和OH等自由基的生成。概述了杂多酸光催化作用的优点和局限性,提出提高光催化反应的量子效率解决方法。
The supported materials of photodegradation of dye wastewaters by heteropoly acid were reviewed in this paper. Reaction mechanism between heteropoly acid and organic matter was generation of electron-hole pair and producing of free radical such as OH. Advantages and limitations of heteropoly acid photodegradation were summarized, and methods were suggested to increase the photodegradation quantum efficiency.
