Br- ions doped Bi2WO6 was prepared using bismuth nitrate Bi(NO3)(3)center dot 5H(2)O and sodium tungstate Na2WO4 center dot 2H(2)O as raw materials by hydrothermal synthesis method. The effect of Br doping on the phase structure, morphology and visible light catalytic properties of Bi2WO6 was investigated using XRD, SEM, TEM, XPS, Raman, PL and DRS. The results indicated that the visible-light-driven photocatalytic performance of Bi2WO6 was greatly enhanced after Br- doping. When Br- was doped with 8% of the amount (percentage of amount of substance), the Bi2WO6 photocatalyst displayed the best photocatalytic performance. It could decompose 96.73% RhB after 40 minutes irradiation, which was 36.32% higher than that of the pristine one.
