目前，由于一系列巨大的环境问题，在太阳光照射下发生的光催化反应引起了世界各国的关注。考虑到太阳光的影响，开发高效的可见光驱动光催化剂势在必行。Bi2WO6是一种新型的可见光驱动光催化剂，其光催化性能严重依赖于其结构、形貌和组成。本文综述了Bi2WO6微纳结构的制备和生长机理的最新研究进展，包括纳米板、纳米粒子、超结构和薄膜。此外，还对掺杂Bi2WO6和Bi2WO6基复合材料的研究进展进行了综述。这些Bi2WO6基微纳米结构在降解有机污染物和杀菌方面表现出不同的光催化性能，并比较了它们的结构和组成对光催化活性的影响。
Currently, the photocatalytic reactions occurring under solar illumination have attracted worldwide attentions due to a tremendous set of environmental problems. Taking the sunlight into account, it is indispensable to develop highly effective visible-light-driven photocatalysts. Bi2WO6is one of newly developed visible-light-driven photocatalysts, and its photocatalytic performance is seriously dependent on its structure, morphology and components. This article features recent research progress in the preparation and growth mechanism of Bi2WO6micro/nano-structures, including nanoplates, nanoparticles, superstructures and thin films. In addition, the advances in the doped Bi2WO6and Bi2WO6based composites have also been overviewed. These Bi2WO6based micro/nano-structures exhibit different photocatalytic performances on the degradation of the organic pollutant as well as the disinfection of the bacteria, and the effects of their structures and components on photocatalytic activities are also compared.
