Research progress in Bi_2WO_6 based nano-photocatalysts

Bi2WO6 has attracted wide attentions in the field of environmental protection due to its excellent visible-light-driven photocatalytic performance.The recent research progress in the preparation of Bi2WO6 micro/nano-structures which include nanoplates,nanoparticles,superstructures,etc,and the modification technologies are summarized in this paper.The effects of shapes and modification process on their photocatalytic activities are also analyzed.Some suggestions are put forward for the further development of Bi2WO6 based nanocatalysts.
