摘      要：Using halide perovskite nanomaterials for solarto-fuel conversion has recently attracted a lot of attention due to their excellent photoelectric ***,severe photogenerated charge carrier recombinations and poor reaction kinetics greatly restrict their photocatalytic *** this study,a ternary WO_(3)/CsPbBr_(3)/ZIF-67 heterostructure was designed for efficient CO_(2) *** results indicate that the Z-scheme charge transfer pathway constructed between WO_(3)and CsPbBr_(3)ensures the effective transfer and separation of photogenerated charge ***,the subsequent surface modification of zeolitic imidazolate frameworks(ZIF-67)with active Co centers further benefits CO_(2)adsorption and ***,the synergistic effects of charge separation and CO_(2)uptake greatly promote the photocatalytic *** optimal WO_(3)/CsPbBr_(3)/ZIF-67 heterostructure yields a CO production of 99.38μmol g^(−1)in 3 h,which is 6.8 times of that produced by CsPbBr_(3).This work will inspire new insights in developing efficient photocatalysts for CO_(2)reduction and even more challenging photocatalytic reactions by elaborately regulating the functional ingredient.
