Graphene oxide (GO) membranes have attracted extensive interest due to their ultrathin thickness, high flux, pore size tunability, superior flexibility, and energy-efficient properties for transporting ions and molecules through the unique 2D channels. Nevertheless, membrane fouling leading to membrane blocking and poor water flux of GO membranes during long-term use are major obstacles for water treatment or desalination applications. In this work, Ag doped GO/titanate nanotube (Ag/GO/TNT) membranes with enhanced visible light degradation abil...
