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.
