摘要
快速的工业化也相应地增加了对能源的需求,光催化剂的研究和发展已经成为一种趋势。钨酸铋半导体材料是近年来研究比较热的一种新型光催化剂。铋系半导体材料的发展,有效地解决了二氧化钛不能吸收可见光的问题,并且具有良好的光催化性能,但是光催化的量子效率低与光生载流子复合仍然是待解决的难题。文章对近年来钨酸铋半导体材料光催化机理及应用热点进行了综述,并对如何进一步提升其性能进行了展望。
Rapid industrialization has increased the demand for energy accordingly, and the research and development of photocatalyst has become a trend. Bismuth tungstate semiconductor is a hot photocatalyst in recent years. The development of bismuth semiconductor materials has effectively solved the problem that titanium dioxide can not absorb visible light and has good photocatalytic performance. However, the low quantum effciency of photocatalysis and photogenerated carrier recombination is still a diffcult problem to be solved. In this paper, the photocatalytic mechanism and application of bismuth tungstate semiconductor materials in recent years are reviewed, and how to improve the properties of bismuth tungstate semiconductor materials are prospected.
