摘要：

Novel Bi2WO6 flower type structure has been successfully synthesized by simple hydrothermal processes. Interestingly, the morphologies and sizes of the Bi2WO6 were controlled by pH values. X-ray diffraction, FT-IR, scanning electron microscope, transmission electron microscope, BET, and UV-visible diffuse reflectance spectra were used to characterize the flower type structure. The results indicated that the Bi2WO6 composed of some uniform slice with side length about 100 nm. The as-prepared Bi2WO6 photocatalysts had excellent photocatalytic activity for the degradation of nitrobenzene under visible light (lambda a parts per thousand yen 400 nm).
