以硝酸铋、钨酸铵为原料，通过水热法制得片状Bi2 WO6，通过KBH4对Bi2 WO6进行还原，生成Bi单质沉积在表面的Bi／Bi2 WO6光催化剂。采用TEM， XRD和UV－Vis DRS分析了催化剂的组成、形貌和光吸收性能。以罗丹明B为模拟污染物，研究了所得Bi／Bi2 WO6的可见光驱动催化活性。结果表明， Bi沉积可有效提高Bi2 WO6可见光催化降解活性。

The flake-like Bi2 WO6 was prepared via a hydrothermal process.KBH4 was used to reduce Bi2 WO6 and Bi particals deposed on the surface of Bi2 WO6 .XRD, TEM and UV-Vis-DRS spectrums were employed to investigate the phase composition, morphology and photoabsorption property of as-fabricated Bi/Bi2 WO6.The visible-light-driven photocatalytic activities of the Bi/Bi2 WO6 were evaluated by the photodegradation of Rhodamine B ( RhB ) .The results showed that Bi particals deposition can enhance the photocatalytic activity of Bi2 WO6 .
