A g-C3N4/nanocarbon/ZnIn2S4 nanocomposite: an artificial Z-scheme visible-light photocatalytic system using nanocarbon as the electron mediator

A g-C3N4/nanocarbon/ZnIn2S4 (CN/C/ZIS) nanocomposite with enhanced photocatalytic H-2 production performance has been successfully synthesized. Based on the experimental results, for the first time, it has been demonstrated that nanocarbon could be integrated into a Z-scheme photocatalytic system and acted as an excellent solid electron mediator.
