Ag3PO4 Particles Decorated into Fly-Ash-Incorporated Electrospun Polyurethane Nanofibers: Simultaneously Enhanced Photocatalytic and Antibacterial Activities

Visible-light-responsive silver-phosphate-sensitized fly-ash particles loaded on polyurethane nanofiber (Ag3PO4–FA/PU NFs) membrane photocatalysts were prepared by electrospinning followed by an ion-exchange method and characterized with state-of-art techniques. With the assistance of Ag3PO4–FA/PU NFs, 98 % of methylene blue (MB) was degraded within 60 min. The combination of FA and Ag3PO4 particles provided simultaneous adsorption and degradation of MB in an aqueous solution, resulting in the fast removal of the dye. Also, the Ag3PO4–FA/PU NFs exhibited excellent antibacterial performance toward Escherichia coli and Staphylococcus aureus bacteria. Thus, the prepared photocatalyst may provide a potential outcome for environmental remediation, especially wastewater treatment applications.
