英文摘要	Regulating the local environment and structure of metal center coordinated by nitrogen ligands (M-N4) to accelerate overall reaction dynamics of the electrochemical CO2 reduction reaction (CO2RR) has attracted extensive attention. Herein, we develop an axial traction strategy to optimize the electronic structure of the M-N4 moiety and construct atomically dispersed nickel sites coordinated with four nitrogen atoms and one axial oxygen atom, which are embedded within the carbon matrix (Ni-N4-O/C). The Ni-N4-O/C electrocatalyst exhibited excellent CO2RR performance with a maximum CO Faradic efficiency (FE) close to 100 % at −0.9 V. The CO FE could be maintained above 90 % in a wide range of potential window from −0.5 to −1.1 V. The superior CO2RR activity is due to the Ni-N4-O active moiety composed of a Ni-N4 site with an additional oxygen atom that induces an axial traction effect. © 2020 Wiley-VCH GmbH
