A Review and Recent Developments in Full‐Spectrum Photocatalysis using ZnIn2S4‐Based Photocatalysts

Nowadays, photocatalytic technology is considered as one of the most efficient methods to solve the problem of the global energy shortage and the pollution of the environment. Among these outstanding photocatalysts, metal sulfide‐based semiconductors have attracted wide attention because of their good chemical stability, simple synthesis method, and relatively narrow bandgaps. ZnIn 2 S 4 (ZIS), as a layered structure ternary metal chalcogenide and a rising material star, has made exciting breakthroughs in the past decades. Recently, studies have shown that a rich variety of ZIS composite nanostructures are developed. This review summarizes the recent advances and development in the design and improvement of ZIS and ZIS‐based photocatalysts in full‐spectrum photocatalytic applications. Furthermore, the applications of ZIS‐based photocatalysts are discussed, such as in photocatalytic hydrogen production, CO 2 reduction, degradation of pollutants, and photocatalytic selective organic transformations under ultraviolett (UV), visible (Vis), and near‐infrared (NIR) light irradiation. In the end, a brief summary and perspectives on the challenges and future directions in the area of ZIS and ZIS‐based photocatalysts are also provided.
