摘要

•All-solid Z-scheme Cd0.5Zn0.5S/CQDs/TiO2 nanofilm (CZS/C/TiO2) is obtained.•CQDs as mediator provide a charge transfer route in the Z-scheme system.•Z-scheme CZS/C/TiO2 nanofilm possesses excellent photocatalytic activity, stability and recyclability.•Photocatalytic enhancement mechanism of CZS/C/TiO2 composite was proposed.
