文摘CO_(2)electroreduction is a promising technique for the management of the global carbon balance by lowgrade renewable electricity.However,the lack of highly efficient and selective catalysts has hampered the development of this area.Herein,we report a poly-phenylenediamine-derived atomically dispersed Ni catalyst as a highly efficient and selective electrocatalyst for the conversion of CO_(2)to CO.
