Electrochemical reduction of CO2 represents a possible solution for transforming atmospheric CO2 to value-added chemicals such as CO or hydrocarbons, but so far it has been hampered by the lack of suitable electrocatalysts. In this work, we design a type of organic-inorganic hybrid material by template-directed polymerization of cobalt phthalocyanine on carbon nanotubes for a high-performance CO2 reduction reaction. Compared with molecular phthalocyanines, the polymeric form of phthalocyanines supported on the conductive scaffold exhibits an enlarged electrochemically active surface area and improved physical and chemical robustness. Experimental results show that our hybrid electrocatalyst can selectively reduce CO2 to CO with a large faradic efficiency (similar to 90%), exceptional turnover frequency (4,900 hr(-1) at eta = 0.5 V), and excellent long-term durability. These metrics are superior to those of most of its organic or inorganic competitors. Its high electrocatalytic activity is also supported by density functional theory calculations.
