Ion-exchange formation of Ag2CO3-Ag3PO4 binary nanostructure on electrospun polyurethane nanofibers for enhanced photocatalytic degradation and antibacterial activities

초록

In this study, a hybrid Ag2CO3-Ag3PO4/PU NFs membrane was prepared by electrospinning followed by ionexchange methods. The obtained samples were characterized by SEM, EDS, XRD, and IR techniques. The Ag2CO3-Ag3PO4/PU NFs membrane composite exhibited excellent photocatalytic performance (100 % of the dye removal within 70 min) towards the degradation of methylene blue (MB) under visible light irradiation. This remarkable performance was mainly due to the efficient separation of the photogenerated charge carriers. In addition, the composite showed good antibacterial performance against Salmonella typhimurium and Staphylococcus aureus. The results obtained from the photocatalytic and antibacterial studies showed that the prepared material can be proposed as a multifunctional material in wastewater treatment and environmental applications.
