Abstract
Fabricating nanostructured fibrous membranes as photocatalyst would facilitate the effective treatment of dyeing effluents. However, creating such photocatalytic nanofibrous membranes has proven tremendously challenging. In this work, we report a scalable strategy to prepare copper-iron bimetal modified polyacrylonitrile (PAN) nanofibrous membranes by electrospinning technology. The resultant PAN membranes exhibit an ultra-fine fiber diameter (600 nm), large surface area (5.34 m2 g−1) and excellent photocatalytic capacity for reactive blue 19, reactive red 195 and acid orange 7 (＞99.99%) within 60 min. The successful synthesis of such intriguing materials could provide a versatile platform for further exploring nano-sized photocatalyst fibrous membranes for degradation of dyes.
