摘　　要：光催化分离膜将膜分离与光催化结合在同一处理单元中,可发挥膜分离作用,同时也可以利用光催化剂高效降解水中的有毒有害污染物,提高膜的抗污染性能和水处理效率。因此是水处理领域的研究热点,并显示出巨大的应用潜力。本文综述了基于二氧化钛(TiO_(2))、氧化锌(ZnO)、石墨相氮化碳(g-C_(3)N_(4))和氧化钨(WO_(3))四种常用催化剂的光催化分离膜的研究概况,重点对光催化分离膜的制备方法和性能进行了总结,光催化分离膜具有良好的发展前景,制备高效、稳定的可见光响应光催化分离膜是未来的发展趋势。Photocatalytic separation membrane has become a research hotspot in wastewater treatment due to its great potential for industrial application.The photocatalytic separation membrane combines membrane separation and photocatalysis in a single unit.Besides playing the role of membrane separation,the photocatalysts can efficiently degrade toxic and harmful pollutants in water and improve the anti-fouling performance and efficiency of the membrane.This paper reviews the recent progress of photocatalytic separation membranes based on four commonly used photocatalysts:TiO_(2),ZnO,g-C_(3)N_(4) and WO_(3).The fabrication and performance of the photocatalytic membranes are elaborated.Photocatalytic separation membranes have bright prospects,and the preparation of efficient and stable visible lightresponsive photocatalytic separation membranes will be the future trend.
