中文摘要：

近年来,铋系半导体材料因其在可见光辐照下对难降解有机物具有良好的催化作用而成为新型光催化材料的研究热点之一。本文综述了国内外铋系光催化剂的研究动态和主要成果。铋系光催化剂在可见光范围内有明显的吸收,具有较好的光催化活性。此外,大多数铋系光催化剂在反应过程中具有较高的稳定性。通过改进制备方法、掺杂负载、构建异质结等技术,可以有效提高铋系半导体材料的可见光吸收性能或抑制光生电子和空穴的复合,从而进一步提高其光催化性能。尽管铋系光催化剂由于其导带位置比氢的氧化还原电位低,但是通过设计合成新的能带结构可使其满足氧化和还原水的能带要求,从而实现铋系光催化剂在光解水制氢中的应用。最后,对铋系光催化剂未来的发展趋势进行了展望,并强调针对特殊用途和结合量化计算方法对开发新型铋系光催化剂的重要性。

英文摘要：

Bismuth-containing semiconductor materials as a novel kind of photocatalysts have attracted much more attention due to their high catalytic activities towards the degradation of organic wastes under visible light irradiation. This paper summarizes the research achievements on Bi-containing semiconductor photocatalysts （e. g. , bismuth oxide, bismuth titanate, bismuth tungstate, bismuth vanadate, bismuth oxyhalide, and so on）. Among the reported Bi-containing photocatalysts, bismuth tungstate and bismuth vanadate are very attractive. Especially, it is shown that many Bi-containing semiconductor photoeatalysts possesses significantly stronger optical absorption properties and higher photocatalytic activities than commercial TiO2 （ P25 ） under visible light irradiation. Moreover, most of Bi-containing semiconductor photocatalysts have good stability. On the other hand, the optical absorption abilities of Bi-containing semiconductor photocatalysts can be obviously improved by chemical modification or constructing heterostructure. Additionally, although the position of conduction band of common Bi- containing photocatalysts is lower than the redox potential of hydrogen, many Bi-containing semiconductor materials can be used as water splitting catalysts by chemical modification. We tried to clarify the relationship between the structure and catalytic performance of the Bi-containing photocatalysts. Prospect on the development of Bi- containing semiconductor photocatalyts is also proposed. It is emphasized that for shortening the peroid of catalyst development, specail Bi-containing photocataylsts should be designed and fabricated by adopting theoretical calculation methods according to their potential applications.
