摘要：
The microsphere Bi2WO6 has been synthesized by a facile hydrothermal method by using Bi(NO3)3 center dot 5H(2)O, H40N10O41W12 center dot 5H(2)O and CO(NH2)(2)(urea) as the starting materials. The as-synthesized Bi2WO6 was characterized by X-ray diffraction (XRD), scanning electron microscopy(SEM), BET and UV-vis absorption spectroscopy. The visible-light-responsive photocatalytic activity of Bi2WO6 microspheres was evaluated by the photo-degradation of RhB under Xe lamp irradiation. The degradation is up to 96% in 3h. The results show that microsphere Bi2WO6 exhibited excellent photocatalytic activity. The reasons for the high photocatalytic activity have been discussed carefully.
