Construction of a CsPbBr 3 modified porous g-C 3 N 4 photocatalyst for effective reduction of CO 2 and mechanism exploration

A P-CN/CsPbBr 3 photocatalyst with a lamellar porous structure was prepared by a high temperature calcination and freeze drying method, and it exhibited superior CO 2 reduction performance under the conditions of full spectrum irradiation.
