Abstract

Abstract Photocatalytic hydrogen evolution (PHE) via water splitting using semiconductor photocatalysts is an effective path to solve the current energy crisis and environmental pollution. Heterojunction photocatalysts, containing two or more semiconductors, exhibit better PHE rates than those with only one semiconductor owing to the altered band alignment at the interface and stronger driving force for charge separation. Traditional binary metal sulfide (BMS)‐based heterojunction photocatalysts, such as CdS, MoS 2 , and PbS, demonstrate excellent PHE performance. However, the recently developed multinary metal sulfide (MMS)‐based photocatalysts possess favorable chemical stability, tunable band structure, and…
