铋系半导体光催化材料的改性
|
摘要
铋系半导体光催化剂是近年来较热门的一类光催化剂,大多具有各向异性的层状结构与合适的禁带宽度,其可见光响应性能好,在环境及能源领域有着广阔前景。然而其依然存在对可见光的吸收有限、光生电子-空穴易复合的问题。介绍了近年来对铋系半导体光催化材料(铋的氧化物、含氧酸盐、卤氧化物等)改性的手段,包括形貌结构调控、表面修饰、构建异质结和组成调控,阐述了改性的效果以及机理,并对其今后发展的前景进行了展望。
Bismuth semiconductor photocatalyst is a kind of popular photocatalyst in recent years, which has anisotropic layered structure and suitable band gap. Their visible light response performance is good. So they have good application prospect in the field of energy and environment. However, they still have many problems, such as low absorption of visible light, the facile combination of photogenerated electron hole. In this paper, recent modifying methods of bismuth semiconductor photocatalytic materials were introduced, including morphology and structure control, surface modification, construction of heterojunction and composition control. The effect and mechanism of modification were discussed, and the further development in the future was prospected.
