Bismuth tungstate can be widely used in catalytic degradation of pollutants.However,the bismuth tungstate prepared today has difficult recycle and poor reusability.Bismuth tungstate/TiO2/PAN electrospun nanofiber membranes were prepared by electrospinning techniques,and it shown well photocatalytic activity.The photocatalytic properties of the membranes were evaluated by its degradation rate of methylene blue.The results showed that the photocatalytic degradation rate of methylene blue reached 95.15% after 4.5h,and the photocatalytic degradation rate remained 81.43% after 6 times of reuse,which indicated that it had excellent photocatalyst Properties and good reproducibility.Thus,the membranes had potential application in sewage treatment.
