Research Progress on Photocatalytic Reduction of CO₂ Based on CsPbBr₃ Perovskite Materials

Abstract Inorganic metal halide perovskites have rapidly become one of the most promising materials in the 21st century and have been widely used in the field of photocatalysis in recent years. In this review, the structure of inorganic metal halide perovskite materials and the related preparation methods of inorganic metal halide perovskite materials with CsPbBr₃ as an example were first described. The application of different CsPbBr₃ composites as photocatalyst in the field of photocatalytic reduction of CO₂ was introduced in detail. In addition, the possible challenges of CsPbBr₃ in the field of photocatalytic reduction of CO₂ are discussed and the application of CsPbBr₃ basal photocatalysts in this field is prospected, which provides a new research direction for improving the photocatalytic performance of inorganic metal halide perovskite materials in the future.
