摘要/Abstract

摘要： 金属离子掺杂、非金属离子掺杂、离子注入以及染料光敏化等方法都可不同程度地实现TiO₂可见光化, 其中非金属掺杂TiO₂可见光催化剂其可见光活性是不以损失UV光激发效率而可以独立存在的. 本文重点介绍了近年来非金属掺杂修饰改性TiO₂光催化剂及本课题组在染料敏化半导体光催化制氢研究方面所取得的一些研究成果, 对非金属离子改性TiO₂光催化剂的效能进行了整理分类. 构建以天然海水和盐湖卤水为应用背景的无电子给体的无机水盐廉价制氢反应体系, 是光催化走向实用化的一个新探索. 本文回顾了无机水盐制氢反应体系构建方面的研究成果, 并对未来光催化分解水的研究工作进行了展望.

Abstract: The progress was made in the area of extending the light absorption of TiO₂ into visible light region by methods of metal cation doping, metalloid anion doping, ion implantation and photosensitization. The particular advantage of metalloid anion doping was that the visible-light-activities can be obtained without the lose of UV-light activities. This article mainly summarized the recent progress in TiO₂ modification by means of metalloid anion doping and the advance in photocatalytic hydrogen production with the photosensitization semiconductor made in our group. In addition, the effect of metalloid anion doped TiO₂ in response to visible light was classified and evaluated. Based on the fact that the construction of inorganic salt-water splitting system without electron donors is a new subject with a view to practical research, the recent advance in the construction of inorganic salt-water splitting system is briefly reviewed while the prospects and existing problems especially for TiO₂ photocatalyst are also addressed.

Key words: TiO₂ photocatalyst, metalloid anion doping, photosensitization, salt solution, review
