摘　　要：Photosensitized heterogeneous CO_(2) reduction(PHCR)has emerged as a promising means to convert CO_(2) into valuable chemicals,however,challenged by the relatively low carbonaceous product selectivity caused by the competing hydrogen evolution reaction(HER).Here,we report a PHCR system that couples Ru(bpy)32+photosensitizer with{001}faceted LiCoO_(2) nanosheets photocatalyst to simultaneously yield 21.2 and 722μmol·g^(-1)·h^(-1) of CO,and 4.42 and 108μmol·g^(-1)·h^(-1) of CH4 under the visible light and the simulated sunlight irradiations,respectively,with completely suppressed HER.The experimental and theoretical studies reveal that the favored CO_(2) adsorption on the exposed Li sites on{001}faceted LiCoO_(2) surface is responsible for the completely suppressed HER.
