Mechanism and tendency of photocatalytic degradation of nanometer TiO_2 for organic contaminations

DENG Zhao-ping, NI Shi-jun, TUO Xian-guo, ZHANG Yong(College of Materials and Bioengineering, Chengdu University of Technology, Chengdu 610059, China)  
It is a new research subject to remove the pollution of organic contaminations by photocatalytic degradation in the environment-protecting field nowadays. Usually, photocatalytic degradation of nanometer TiO_2 for organic substances may take place only in the range of ultraviolt. In the paper, the route to move the range of the light of photocatalytic degradation from ultraviolet light to vision light by donor doping is stated. The mechanism of photocatalytic degradating organic contaminations and the research tendency of removing the pollution of pesticide residue with TiO_2 nanometre materials are intruduced .
