| 摘 要： | 概述了近年来利用离子掺杂、染料光敏化和半导体复合等方法对二氧化钛进行可见光化改性,以提高其可见光催化分解水制氢效率的研究进展。分析了改性后二氧化钛吸收可见光的原理,详细介绍了改性二氧化钛可见光催化分解水制氢的研究近况。众多研究表明,与染料光敏化和半导体复合等改性方法相比,离子掺杂法使二氧化钛催化剂具有更高的效率和更好的光稳定性,因此掺杂改性将成为可见光催化分解水制氢研究的主要方向。

| Abstract: | Hydrogen production by photocatalysis under visible light is an interesting route,which can resolve both fuel and environment problem.Recent progress of hydrogen production under visible light with modified TiO_2 was briefly reviewed.Modification of TiO_2,including doping,surface sensitization and composite semiconductor etc.can extend the energy range of photoexcitation for TiO_2 system.The mechanism of photoexcitation in visible light and the progress of three modification methods of TiO_2 were analyzed.Progress of hydrogen evolution from water using modified titania under the visible light was discussed in detail.Many researches showed that ion doping TiO_2 is the most efficient and stable approach among the three modification methods,so doping becomes a main direction. |
