Nickel phosphonate-derived Ni2P@N-doped carbon co-catalyst with built-in electron-bridge for boosting photocatalytic hydrogen evolution

Ni 2 P@CN is employed to construct a novel Cd 0.5 Zn 0.5 S/Ni 2 P@CN composite photocatalyst which guarantees highly efficient interfacial charge separation and transfer between Ni 2 P@CN and Cd 0.5 Zn 0.5 S, resulting in enhanced photocatalytic activity.
