The invention discloses a preparation method and application of a Cu 2 O/Bi 2 O 2 CO 3 semiconductor heterojunction composite silk fibroin fiber membrane. On the one hand, the present invention synthesizes a semiconductor heterojunction with excellent photocatalytic performance through a simple reduction solution chemical approach; The silk fibroin sponge is dissolved in formic acid according to a certain proportion and mixed evenly to obtain a silk fibroin-formic acid solution. Then, using silk fibroin as the carrier, the semiconductor heterojunction powders with different ratios were uniformly dispersed in the silk fibroin-formic acid solution by ultrasonic to prepare the mixed spinning solution, which was prepared by electrospinning equipment under certain spinning conditions. A novel semiconductor material composite silk fibroin nanofiber membrane. The composite nano-film of the invention has excellent performance of photocatalytic degradation of chloramphenicol, and can be used for water treatment of organic pollution. |
