摘　　要：由于全球的工农业的迅速发展,水污染已成为人类所面临的最大危机。基于半导体光催化法是治理水污染的绿色技术之一,能够有效地降解和去除水中的污染物。在众多光催化材料中,金属氧化物半导体由于其具有低毒性、高稳定性和对水溶液中化学腐蚀的较高的抵抗力等优点,而被科学家们广泛地研究和应用。其中,三元组分的金属氧化物因其具有较窄的禁带宽度和可见光响应性质,在光催化降解领域上的能力已经超过其他的金属化合物。本文系统地介绍了两种典型的三元金属氧化物——钨酸铋和钼酸铋,围绕着基于钨酸铋和钼酸铋的复合型催化剂的制备和在光催化降解废水处理领域中的应用以及发展进行了综述,提出了目前关于钨酸铋和钼酸铋的复合材料的设计、机理研究和改性修饰方法中的所存在的主要问题,并对未来的发展趋势进行了展望。Due to the rapid development of industry and agriculture worldwide,water pollution has become the most important crisis facing humanity.Semiconductor-based photocatalytic method is one of the green technologies for controlling water pollution,which can effectively degrade and remove pollutants in water.The widespread use of metal oxide semiconductors in numerous photocatalytic materials,which stems from their salient features such as low toxicity,high stability,and resistance to chemical corrosion in aqueous solution.Among these,ternary metal oxides have surpassed other metal oxides in terms of photocatalytic activity under visible-light irradiation due to their reduced band gaps.This article systematically describes two typical ternary metal oxides-bismuth tungstate and bismuth molybdate.The preparation as well as the application and development of composite catalysts based on bismuth tungstate and bismuth molybdate in the field of photocatalytic degradation wastewater treatment are reviewed.The main problems in the design,mechanism research and modification methods of the composite materials on bismuth tungstate and bismuth molybdate are proposed,and the future development trend is prospected.
