Todays, semiconductor nanomaterials are used extensively as an effective photocatalyst for organic compound degradation. The main challenge in photodegradation is the separation of nanomaterials from treated solutions. To overcome this problem a novel cross-linked membrane composedof thin-film polyamide/silver/reduced graphene oxide (PA/Ag/rGO) was successfully deposited on the surface of cellulose acetate membrane (CA). The prepared Ag/rGO nanocomposite and Ag/rGO/CA/TFC membranes were characterized using SEM and FTIR. The crystal structure of Ag/rGO was confirmed by XRD. EDX analysis indicates the successful deposition of Ag/rGO nanocomposite in thepolyamide thin film(TFC) matrix. The high hydrophilicity of the Ag/rGO/CA/TFC membrane was confirmed by contact angle measurements, which decreased from 76 ± 5° to 45 ± 1 upon modification. The prepared membranes were applied for photocatalytic degradation of methylene blue dye (MB). Within 20 min, the synthesized Ag/rGO nanocomposite achieved fast degradation equilibrium with an efficiency of 98%,Ag/rGO/CA/TFC membranes displayed a 92 % efficiency, showing the remarkable ability for decomposition of MB and excellentefficiency for wastewater treatment. The degradability was greatly boosted with a high efficiency even after four runs. The increased photocatalytic activity of thin film (TFC) membrane-covered Ag/rGO nanocomposites could be useful in energy and environmental applications, as well as a potential choice for superior wastewater dyes removal.
