CdIn2S4-based advanced composite materials: Structure, properties, and applications in environment and energy – A concise review

Recently, ternary metal chalcogenides are widely used as an excellent material for energy generation and environmental remediation. CdIn2S4 (CIS) is a ternary n-type semiconductor acts as an active catalyst because of the presence of the In3+ ions. CdIn2S4 is a highly efficient, low-cost photocatalyst due to its chemical stability, ease of synthesis, high durability, and tunable band gap. CIS photocatalysts gain a lot of attention due to the absorption of superior visible light. Various modifications, such as element doping, co-catalyst deposition, modifications of surface, heterojunction construction enhanced the catalytic performance of CIS. This review describes the applications of CIS and CIS based materials for CO2 reduction, environmental remediation, photocatalytic organic transformations, photoelectrochemical, and H2 production by water spilling. At last, challenges and future perspectives are also provided for further development of CdIn2S4 for energy and environmental applications.
