ZnIn2S4-based heterostructured photocatalysts for CO2 reduction: A mini review

Abstract

ZnIn₂S₄ (ZIS)’s superior photocatalytic CO₂ reduction efficacy, coupled with its distinct layered architecture and narrow energy band profile, makes it an intriguing target for CO₂ conversion studies. This article evaluates the photogenerated charge transfer mechanism and photocatalytic CO₂ reduction (PCR) efficacy of varied ZIS-based heterostructure catalysts. ZIS-based heterojunctions are initially classified, ensuing discourse on advanced engineering techniques enhancing heterojunction phot catalysts’ PCR functionality like co-catalyst incorporation and morphologic manipulation. The concluding section provides an overview of the present study state and future progression in regard to ZIS-based heterostructured photocatalysts for PCR.
