Progress in research of visible-light-induced nano TiO2 photocatalysts
Abstract:Nanostructured titania is activated only under UV light irradiation because of its large band gap. Therefore, it is very significant to explore efficient approaches to extend its response from UV to visible light region, and find visible-light-induced titania photocatalysts. This paper presents a brief review on the progress in research of visible-light-induced nano TiO2 photocatalysts by the modifications of titania which include metal-doped, nonmetal-doped and photosensitization.
Keywords: TiO2 visible-light-induced metal-doped nonmetal-doped surface photosensitization
