At present, film photocatalytic is studied mostly for treating with water pollution. Because the film will not bring the secondary pollution, and can be used again. ZnO film and TiO_2 film is mostly used as photocatalyzer, but they have some disadvantage, as they can only absorb little of the sun-light energy, the photoluminescence exciton compounds mostly, and they can be eroded easily by light. Complex semiconductor film is a good method to ravel out these problems.

目前，在光催化治理水污染方面，膜的光催化是一个研究的热点，因为膜催化不存在二次污染且便于回收和重复利用，研究较多的是ZnO薄膜和TiO_2薄膜，但是单一组分的薄膜存在光能利用率低，光激子复合率高，易发生光腐蚀等缺点，复合膜是解决该问题的有效途径，我们提出了全新的复合薄膜的制备方法—混合溶胶法。

Which not only avoid the filtration and resuspension of the photocatalysts, also has advantage for the design of photocatalytic reactor.
