摘要
含铋光催化材料因其能吸收可见光、催化活性高而具有广阔的应用前景。本文主要回顾了含铋光催化材料近年来的研究概况,详细介绍了铋氧化物、卤氧化铋及钛酸铋、钨酸铋、钒酸铋、钼酸铋、铁酸铋等光催化剂的结构、制备和光催化性能,重点对光催化性能的改进方法进行了综述,包括制备方法的改良、催化剂的掺杂改性及复合催化剂的制备等;最后针对进一步提高光催化剂整体性能、实现工业化应用两点,提出了未来可以利用多元元素掺杂、多元半导体复合进行改性和负载于某些载体制备整体催化剂进行改良的观点。
Bismuth-containing photocatalysts can be used in many fields because of narrow band gap and ability of adsorbing visible light. In this paper , the latest research status and progress of bismuth-containing photocatalysts are reviewed. Bismuth oxide , halide bismuth oxide , bismuth titanate,bismuth tungstate,bismuth vanadate,bismuth molybdate and bismuth ferrite are introduced and the methods of improving photocatalytic performance are highlighted,including improvement of synthesis methods,photocatalysts doping and preparation of photocatalyst composites. Finally,the research directions of bismuth-containing photocatalysts are presented,aimed at improving overall performance and realizing industrial application of bismuth-containing photocatalysts , such as preparing multi-doped photocatalysts,multiple photocatalyst composites and supported catalysts.
