摘要
铋系半导体材料是近年来研究较热的一类新型光催化剂,因其具有独特的层状结构和合适的禁带宽度,而表现出了良好的太阳光催化性能,在环境污染物去除方面展现出极大的潜力。本文综述了近年来铋系光催化剂(氧化铋、硫化铋、钨酸铋、钼酸铋、钒酸铋、卤氧化铋等)在环境污染物去除方面的最新研究进展,介绍了几类常见的铋系半导体材料及其制备方法,归纳和总结了铋系光催化剂在大气净化、有机废水处理、重金属离子处理和杀菌等方面的应用,同时对今后铋系光催化剂在环境污染去除方面的应用进行了展望。
In recent years,Bi-based semiconductor materials have gained considerable attention. Their unique layered structure and suitable band gap endowthem with superior visible light photocatalytic activities,which is promising in environment pollutants removal. This article mainly reviews the recent advances in environment contaminants removal with Bi-based photocatalysts. We first introduce several well-known Bi-based semiconductor materials and their preparation methods,and then summarize their applications for air purification,organic wastewater treatment,heavy metal ions removal,disinfection,and finally discuss the major problems in the field of bismuth-based photocatalysts,and prospect their further development in the future.
