Abstract:

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: TiO2, ZnO, g-C3N4 and WO3. The fabrication and performance of the photocatalytic membranes are elaborated. Photocatalytic separation membranes have bright prospects, and the preparation of efficient and stable visible light-responsive photocatalytic separation membranes will be the future trend.

Key words: photocatalysis, membranes, separation, catalyst, waste water, pollution

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(TiO2)、氧化锌(ZnO)、石墨相氮化碳(g-C3N4)和氧化钨(WO3)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。
