Abstract
The global energy crisis has driven significant research into renewable energy sources, and photoelectrochemical (PEC) water splitting stands out as one of the most promising solutions for hydrogen production. Among the various materials developed for PEC water splitting, ternary metal sulfides, particularly ZnIn2S4, have garnered considerable attention due to their unique combination of electronic, optical, and chemical properties. This paper presents a comprehensive analysis of the structure and properties of ZnIn2S4, explores modification strategies for ZnIn2S4-based photoanodes, and discusses their application in PEC water splitting. Furthermore, we address the challenges and limitations of ZnIn2S4-based photoanodes and highlight prospects for their future development.
