Description
Summary:[Display omitted] •A novel g-C3N4/CNTs/Ag3PO4 Z-scheme photocatalyst was successfully prepared.•The g-C3N4/CNTs/Ag3PO4 exhibited excellent photocatalytic performance.•The CNTs can act as the electron mediator in the g-C3N4/CNTs/Ag3PO4 Z-scheme system.•The photocatalytic mechanism of g-C3N4/CNTs/Ag3PO4 Z-scheme photocatalyst was proposed. A novel g-C3N4/Carbon nanotubes/Ag3PO4 (g-C3N4/CNTs/Ag3PO4) Z-scheme photocatalyst was prepared to investigate the photocatalytic performance. The CNTs uniformly distribute between g-C3N4 nanosheets and Ag3PO4 nanoparticles and could act as the electron mediator between g-C3N4 and Ag3PO4 in the Z-scheme reaction process to significantly improve the photocatalytic performance of nanocomposite g-C3N4/CNTs/Ag3PO4. Meanwhile, g-C3N4/CNTs/Ag3PO4 showed a highly photocatalytic stability and a universal activity for photocatalytic degradation of dyes.
