摘要:
The effects of photocatalytic degradation of dyes both in single.TiO2 colloidal system and Fe2O3-TiO2 complex colloidal system have been investigated in the sunlight respectively. The goal of the study is to vertify the TiO2 coupled with short-bandgap semiconductor Fe2O3 as catalyst, which not only extends the photoresponse of TiO2 to visible light but also enhances the efficiency of charge separation, and has a higher photocatalytic activity than single TiO2 system, the preliminary experimental results show that the complex system can improve the effect of photo-catalytic degradation.
