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.
