Progress of Preparation of Bi_2WO_6 for Visible-light Photocatalyst

Preparation of Bi2WO6 for visible-light photocatalyst has been reviewed.The preparing methods include solid state reaction method,molten salt method,liquid reaction method,amorphous complex method,hydrothermal method,microemulsion hydrothermal process,and solvent-thermal method,among which hydrothermal method is most widely employed for its convenience to prepare Bi2WO6 of different structures and shapes by introducing templates such as surfactants and other methods have special application situation for their own advantages.
