Conventional water treatment processes suffer from low degradation efficiency and severe secondary pollution, and cannot meet the discharge standards of industrial wastewater with complex compositions and fluctuating concentrations. This is the core reason for the rapid popularization and practical application of green photocatalysis technology. Visible light photocatalysis is driven by clean solar energy, featuring environmental friendliness, mild reaction conditions, and no demand for high-temperature and high-pressure auxiliary equipment, which makes it highly suitable for large-scale treatment of industrial dye wastewater. Polyacrylonitrile (PAN) nanofiber membranes possess unique merits including low cost, high flexibility, stable structure, and abundant pores. Through multi-step precise chemical modification to support heteropolyacid active components, recyclable visible-light-responsive photocatalytic membrane materials with high degradation efficiency and excellent stability can be fabricated.PAN photocatalysis, Nanofiber membrane, Preparation, Equipment research
