Abstract

Abstract:

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.

Key words: Photocatalytic oxidation, Photocatalytic degradation, Complex Fe₂O₃-TiO₂ particle
