摘要: TiO2 光催化复合分离膜是近几年出现的一种集光催化和膜分离作用于一体的新型多功能复合膜, 多用于水处理中. 将光催化剂 TiO2 负载于膜表面或者内嵌于膜中, 制备成光催化复合分离膜, 不仅解决了 TiO2 的回收问题, 且能在一定程度上缓解或者消除膜污染问题; 在发挥光催化和膜分离作用的同时, 还能产生一系列的协同作用, 以加强污染物的处理效果. 本文综述了光催化复合分离膜的作用机理和类型, 重点评述了目前复合膜的制备方法, 并对其性质及应用做一总结, 最后针对复合膜目前存在的问题对其今后的发展方向提出展望.

Abstract: TiO2 photocatalytic separation membrane is a kind of novel multifunctional composite membrane integrating photocatalysis and separation technologies for water treatment. TiO2 photocatalyst is loaded on the membrane surface or entrapped in the membrane to obtain the composite membrane that makes the TiO2 recovery problem solved. More significantly, the membrane is efficient to maintain high flux of membranes as the presence of TiO2 photocatalyst can reduce the membrane fouling problem which is a hindrance in the development of membrane process. Moreover, some synergistic effects can also be produced, and thus the efficiency of water treatment is enhanced greatly. A comprehensive review of TiO2 photocatalytic separation membrane is conducted with an insight into its types, preparation methods, properties, and its application. In view of the existing problems, the prospects for future development of TiO2 photocatalytic separation membrane are also proposed.
