Electrochemical CO2 reduction into CO or high-value products is regarded as a feasible pathway for energy conversion, which has attracted universal attention in recent years [1-3].However, the reduction of CO2 molecule is a thermodynamically uphill process,which involves multiple elemental steps and the competition of hydrogen evolution reaction (HER) in aqueous solution.Therefore,much effort has been devoted to the development of catalysts with high activity, selectivity, and stability towards various chemicals [4-6].Among the numerous catalysts, metal porphyrins and metal phthalocyanines with distinct advantages in easy accessibility,chemical stability, and structural tunability were reported with ultra-high selectivity [7-13].However, the performance of most metal-porphyrin catalysts is hindered by low active site utilization due to its stacking and aperiodicity structures.Besides, most molecular catalysts had been applied in homogeneous catalysis systems.The necessary organic solvents and the difficulty of separating and recycling catalysts greatly limited their large scale applications [7-9].
