This review summarizes the superiorities and utilizations of 2D materials for photoelectrochemical water splitting including transition metal dichalcogenides, graphene, graphdiyne, black phosphorus, layered double hydroxides, g-C 3 N 4 , MXenes.

Global environmental pollution and energy crisis have been regarded as important issues in recent years, making people aware of the need to develop environmentally friendly sources. ZnO photocatalysts play a key role development hydrogen generation from water splitting via photocatalytic strategy. generally exhibits n-type conductivity, difficulty preparing p-type for forming stable p–n junctio...
