Due to the complexity of harmful wastewater components, environmental and multifunctional materials are required for sewage purification. In this paper, the kidney-bean-skin-like hydrophilic porous polyacrylonitrile/reduced graphene oxideg-poly amidoxime loaded Ag+ (H-PPAN/rGO-g-PAO@Ag+/Ag) composite nanofibers membrane is fabricated by combining electrospinning and hydrolysis. The method of chelation and heat treatment can be used for forming a Schottky junction between rGO-g-PAO@Ag+ and Ag. After five cycles tests, it exhibited outstanding mechanical property ensuring the filtration and purification performance of H-PPAN/rGO-g-PAO@Ag+/Ag composite nanofiber membrane (i.e. the tensile strength was still 7.21 MPa and the elongation was 61.53%) for simulated wastewater. Its catalytic efficiency for dyes Benzoic acid (BA), Rhodamine B (RhB), Methylene blue (MB), and Methyl orange (MO) was up to 99.8%, 98%, 95%, and 91%. The antibacterial rate was 100% against E. coli, and 99% against S. aureus. More importantly, the photocatalytic and antibacterial PAN based nanofiber membrane can be simply scaling up, which provides the membrane with great potential in highly efficient wastewater treatment and augmenting water supply.
