CO2 electroreduction is a promising technique for the management of the global carbon balance by low-grade renewable electricity. However, the lack of high efficient and selective catalyst has frustrated the development of this area. Here, we report a poly-phenylenediamine-derived atomically dispersed Ni catalyst as a highly efficient and selective electrocatalyst for the conversion of CO2 to CO. The catalyst exhibited efficient production of CO with high Faradaic efficiency (FE) (90%) and a large current density of 11.6 mA cm-2 at −0.8 V vs. reversible hydrogen electrode (RHE). An excellent turnover frequency (TOF) of 3079 h−1 for electroreduction of CO2 was also achieved at −0.8 V vs. RHE.
