摘　　要：钨酸铋因其独特的层状结构和适合的禁带宽度,在可见光下表现出较高的光催化活性,成为近年来新型光催化剂的研究热点之一。文章主要从结构角度总结了钨酸铋光催化材料的研究动态和研究成果;通过半导体复合、贵金属负载、碳负载等改性方法,提高钨酸铋的光催化性能,并简要评述了Bi_2WO_6光催化材料在制备及应用中面临的挑战,指出了未来的发展趋势。Bi_2WO_6光催化材料的研究将为光催化去除和降解有机污染物开辟一条新的途径,在环境净化和新能源开发方面具有非常重要的实用价值。Bi2WO6 has a high photo catalytic activity under visible light due to its unique layered structure and suitable band gap, has become one of the hot spots in recent years. The developments and achievements of Bi2WO6 photo catalysis research have been summarized fi-om a structural perspective. Also, modification methods, such as the composite semiconductors, noble metal loading, and grapheme composite, which further improve the photo catalytic properties of bismuth oxyhalide, are discussed. Besides, the current challenges and future perspectives in their preparations and applications are also briefly outlined. The study of Bi2WO6 photo catalytic materials will open up a new way for photo catalytic removal and degradation of organic pollutants, which is of great practical value in the field of environmental purification and new energy development.
