Abstract
- Construction of photoactive nanofibrous membranes for effective treatment of dyeing effluents is critical to meet the great demands of environmental protection in textile industry, yet still remains a big challenge. In this work, we report a cost-effective strategy to create rechargeable photoactive cellulose nanofibrous membranes (BPTCD-CeNM) under mild conditions that can effectively and repeatedly produce hydroxyl radicals for dye degradation. The principle of this design is that BPTCD-CeNM could store photoactivity under UV light irradiation and release hydroxyl radicals under dark conditions. The membranes possess an ultra-fine fiber diameter (275 nm), large surface area (3.06 m<superscript>2</superscript> g<superscript>−1</superscript>) and excellent degradation performance for reactive red 195, reactive yellow 4 and acid blue 7 (> 99.99% within 60 min). The successful fabrication of such materials may open up new avenues for designing and constructing highly efficient photoactive membrane materials for environmental applications.
