Abstract

Four different sols, pure TiO₂, F doped TiO₂, Fe doped TiO₂, and F-Fe co-doped TiO₂ sols, were prepared by peroxidation at low temperature. The crystal structure, morphology, light adsorption, and photocatalytic properties of the pure and doped TiO₂ were examined by X-ray diffraction, transmission electron microscopy, and ultraviolet-visible spectrophotometry. The relationship between the average size, crystal type, range of visible light absorption, and photocatalytic activity and content and type of doped ions were investigated. The results showed that the average size of the F-Fe co-doped TiO₂ composed of both the anatase and rutile phases was the same as that of pure TiO₂. Furthermore, the visible light photocatalytic activity of the F-Fe co-doped TiO₂ was significantly improved over pure TiO₂, F-doped TiO₂, and Fe-doped TiO₂ due to the large red shift in the light adsorption edge. © 2011 Springer Science+Business Media, LLC.
