Heteroatom P filling activates intrinsic S atomic sites of few-layered ZnIn2S4via modulation of H adsorption kinetics for sacrificial agent-free photocatalytic hydrogen evolution from pure water and seawater

Kinetic-oriented design of ZnIn 2 S 4 via P-filling can modulate the surface activity by diminishing H adsorption–desorption barrier for sacrificial-free H 2 evolution.
