Constructing a visible-light-driven photocatalytic membrane by g-C3N4 quantum dots and TiO2 nanotube array for enhanced water treatment

Abstract Photocatalytic membranes that driven by visible light are highly desired for water treatment. Here g-C3N4 quantum dots (QDs) assembled into TiO2 nanotube array (TNA) membranes were fabricated for the first time as a visible-light-driven g-C3N4/TNA membrane. Benefiting from the synergistic e...
