Abstract
Bismuth Tungstate has been widely used in catalytic degradation of pollutants. However, the low specific surface area make it difficult to use. Herein, bismuth/tungstate/polyacrylonitrile (PAN) nanofiber was prepared by electrospinning. After oxidation treatment, the bismuth tungstate/ PAN composite nanofiber membrane showed photo catalytic activity. The photocatalytic property of resulting membrane was evaluated by the photodegradation of methylene blue. The results showed that the photodegradation rate reached to 95.53% after 4.5h. The photodegradation rate of the membrane still preserved 83.88% after 8 times reuse, indicating its reusability. Thus, the visible-light-catalyst has potential application in sewage treatment.
