摘要
钼酸铋作为一种具有天然矿石结构的复合氧化物,因带隙宽度小,对可见光有响应被广泛关注。其中γ-Bi2MoO6在钼酸铋所有相态里光催化性能最好,可以用于有机污水处理,空气净化等方面,但是其低下的量子产率限制了其光催化性能。近年来人们为了提高其光催化性能研究了其多种形貌结构和其与二氧化钛复合性能的变化。本文综述了钼酸铋半导体及其与二氧化钛复合的制备方法,总结了钼酸铋及钼酸铋氧化钛复合光催化剂的改性方法,并展望了其在污水处理、光电转换和卫生保健等方面的应用。
Bismuth molybdate, as a composite oxide with natural ore structure, is widely concerned because of its small band gap width and its response to visible light. Among them, the photocatalytic performance of past-Bi2MoO6 is the best in all phase states of bismuth molybdate, which can be used in organic sewage treatment, air purification, etc., but its low quantum yield limits its photocatalytic performance. In order to improve its photocatalytic properties, the changes of its morphology and structure as well as its composite properties with titanium dioxide have been studied in recent years. In this paper, the preparation methods of bismuth molybdate semiconductor and its composite with titanium dioxide are reviewed, the modification methods of bismuth molybdate and bismuth molybdate titania composite photocatalyst are summarized, and their applications in sewage treatment, photoelectric conversion and health care are prospected.
