SYNTHESIS OF Fe3+/TiO2-POROUS-NANOFILM AND RESEARCH OF IT’S PHOTOCATALYTIC CHARACTER

doi:10.7517/j.issn.1674-0475.2003.06.426

Abstract

Abstract: In the research,Fe³⁺/TiO₂ porous nanofilm has been synthesized by using Sol Gel method.The photocatalytic results show that nanocrystalline TiO₂ co doped with Fe³⁺ dopants enhances the photoreactivity significantly. The effects of the Fe³⁺ dopants in nanocrystalline TiO₂ particles on the photocatalysis were studied by using the photoelectrochemical method.Fe³⁺ serves as charge carrier traps and promote holes interfacial transfer reaction.

Key words: Fe³⁺/TiO₂-porous-nanofilm, Sol-Gel method, photocatalysis-degradation
