摘　　要： 非均相光催化氧化是一种催化剂易于回收利用且研究广泛的高级氧化技术。本文综述了多金属氧酸盐(POMs)非均相光催化降解废水中有机污染物的研究现状。该类非均相光催化剂主要包括负载型POMs(载体主要有半导体氧化物、离子交换树脂和分子筛)、POMs复合膜材料、不溶性盐和多元复合物。讨论了其制备方法、降解效果、反应机理和重复使用性。最后,指出了该领域未来可能的研究方向,为该领域的进一步研究提供参考。 The heterogeneous photocatalytic oxidation had been widely investigated as an advanced oxidation technology with easily recyclable catalyst. In this paper, the research status of to degradation of organic pollutants in wastewater by heterogeneous photocatalysis with polyoxometalates （POMs） was reviewed. Heterogeneous photocatalysts included immobilized POMs （using semiconductor oxides, ion exchange resins and molecular sieves as carrier）, POMs composite film materials, insoluble salt and multiple composites. Their preparation methods, degradation effects, reaction mechanisms and reuse performances were discussed. Finally, several possible research directions were pointed out, providing reference for further research in the field.
