| 英文摘要 | In order to obtain visible light response, doping or modifying titania by nonmetal elements such as nitrogen has been investigated extensively in recent years. In this paper, recent progress in mechanism of titania doping by nitrogen, carbon, sulphur, fluorine is reviewed. Methods for preparing nitrogen doped titania are follows: i) reduce titania by ammonia gas under high temperature; ii) sputter titania target in nitrogen gas; iii)pulsed laser deposition in nitrogen gas; iv) mechanochemical processing titania in ammonia; v)direct oxidation titanic nitride; vi)forming organic titanic nitride and then thermal treated; vii)hydrolysis a titanic precursor in ammonia solution then thermal treated the precipitate. Structure and mechanism of visible light response of the nitrogen doped titania are discussed according to literature reports although there had many inconsistent conclusions. Narrowing the band gap of titania or forming a new isolated level in band gap may be the most probable reason for visible response. Titania doping by carbon, sulphur or fluorine can also give rise to visible light response and high photo efficiency, but there had many inconsistent conclusions too. |
