Abstract: With the development of chemical industry, the discharge of industrial wastewater increase gradually, which has caused serious environmental pollution. Therefore, developing an efficient treatment technology to solve this problem is urgently needed. Photocatalysis is an efficient strategy to remove organic pollutants in aqueous condition. TiO2 is one of the most excellent photocatalytic material to be used in pollutant degradating, due to its higher chemical stability, photocatalytic activity and environmental friendliness. However, TiO2 particles are aggregated easily in aqueous media and difficult to be recycled, which hinders its practical applications. Dispersing TiO2 nanoparticles on the surface of mineral materials can reduce the aggregation of TiO2, increase the number of surface active sites, and improve its photocatalytic activity. This paper reviews new research progress of mineral supported TiO2 composites in photocatalytic degradation of organic pollutants.

摘要： 随着化工行业的发展，工业废水的排放不断增加，对环境造成了极大污染。因此，需要一种高效的处理技术来解决这一问题。多相光催化是去除水环境中有机污染物的一种高效、可持续发展的技术。TiO2具有化学稳定性好、无毒无害、光催化活性高等特点，是目前最具发展前景的光催化材料之一。然而，TiO2在水溶液中容易团聚，回收困难，其实际应用受到了限制。将TiO2纳米颗粒分散在矿物材料表面，可以减少TiO2的团聚，增加表面活性位点，提高TiO2的光催化活性。综述了矿物负载TiO2复合材料在光催化降解有机污染物中的最新研究进展。
