Abstract

Abstract : Membrane fouling is still the main obstacle for the wider application of membrane processes. Abstract : Membrane fouling is still the main obstacle for the wider application of membrane processes. In this study, different amounts of silver modified graphitic carbon nitride (Ag/g-C3 N4 ) were firstly introduced into polyethersulfone (PES) membranes by blending via a phase-inversion method. The impacts of Ag/g-C3 N4 addition on the membrane morphology, filtration and photocatalysis antifouling properties of Ag/g-C3 N4 /PES nanocomposite membranes were systematically studied. The results illustrated that the addition of Ag/g-C3 N4 could make the finger-like voids in Ag/g-C3 N4 nanocomposite membrane longer and wider, increasing the hydrophilicity and filtration property of the nanocomposite membrane. Also the addition of Ag/g-C3 N4 nanosheets could endow the nanocomposite membranes with excellent antibacterial, photocatalytic dye degradation and antifouling properties under visible light irradiation.
