Graphene oxide (GO)membranes are emerging for water treatment.Meanwhile, challenges remain due to membrane fouling and their instabilityin aqueous solutions. Herein, a novel GO-based mixed-dimensional membranewith superior antifouling and nonswelling properties was preparedby assembling two-dimensional (2D) GO nanosheets and zero-dimensional(0D) copper(I) oxide-incorporated titanium dioxide photocatalyst (CT).The decoration of CT in GO nanosheets tuned the microstructure andsurface hydrophilicity while creating more transport channels in CT/GOmembranes. This resulted in a high water permeance of 171.5 L m(-2) h(-1) bar(-1) andimproved selectivity to various dye molecules (96.2-98.6%).Due to the significantly enhanced antibacterial properties of theCT nanoparticles, the growth of bacteria on the surface of the CT/GOmembrane was suppressed (threefold less than that on the GO membrane).Moreover, the embedding of photocatalysts also allowed CT/GO membranesto exhibit & SIM;9-fold improvement in antibacterial activity andorganic dye degradation performance under visible-light irradiation.This study offers a powerful solution to enhance the nanofiltrationperformance and antibacterial properties of GO membranes toward practicalapplications.
