Flake BiOBr was prepared by one-step hydrothermal method using NaBr and Bi(NO 3 ) 3 •5H 2 O as raw materials. The structure of the samples was characterized by means of XRD, SEM, UV-VIS. The photocatalytic activity of BiOBr was studied with methylene blue as probe. The results show that BiOBr with high exposure {102} can be obtained when the hydrothermal temperature of the product is 160°C and the hydrothermal time is 24 h. Under visible light, the degradation rate of methylene blue was over 98%. When the catalyst was reused three times, the degradation rate could still reach 80%.
