Factors affecting photo catalytic activity of TiO_2 and measures improving its potocatalytic performance

REN Cheng-jun~1,3 ,LI Da-cheng2,ZHONG Ben-he1,ZHOU Da-li2,LIU Heng2,GONG Jia-zhu4 (1.Chemical Engineering College Sichuan University,Chengdu 610065) (2.Material College Sichuan University,Chengdu 610065) (3.The Faculty of Chemistry Sichuan University,Chengdu 610064) (4.Sichuan Longmon Titanium Industry Co.Ltd,Mianzhu City 618200)  
In this paper,the various factors influencing photo catalytic activity of TiO_2 are analyzed in detail.These factors include:the properties of TiO_2itself,modifications of nano-TiO_2,the technical conditions of photo-reactive system,photocatalytic reactors ,and inducted other energy fieles ,etc.Themeasures enhancing photocatalytic activity of nano-TiO_2 are discussed.Some existing problems which are to be solved in the future study are pointed out.
