摘要
纳米TiO2 具有光催化性能 ,利用太阳光能将有机污染物矿化为CO2 和H2 O。从TiO2 的光催化降解机理入手 ,讨论了影响纳米TiO2 光催化性能的因素及提高光催化性能的方法 ,列举了纳米TiO2 光催化降解处理染料废水、农药废水、含有表面活性剂的废水以及含油废水的应用。
Nano TiO 2 has potential to degrade some organics into CO 2,H 2O and other small molecules with solar energy due to its photocatalytic capability.Influencing factors on photocatalytic capability of nano TiO 2 and methods of improving photocatalytic capability as well as its application in treatment of dyestuff wastewater,pesticide wastewater and wastewater containing surfactant or oil are discussed extensively according to photo catalytic degradation mechanism of TiO 2.And some other problems are also mentioned that need to be solved.
