Summary: An axial traction strategy was developed to optimize the electronic structure of the M-N-4 moiety, leading to atomically dispersed nickel sites coordinated with four nitrogen atoms and one axial oxygen atom embedded within the carbon matrix (Ni-N-4-O/C). This Ni-N-4-O/C electrocatalyst exhibited excellent CO2RR performance with a high CO Faradic efficiency close to 100% at -0.9 V, maintaining the CO FE above 90% in a wide potential window. The superior CO2RR activity is attributed to the axial traction effect induced by the Ni-N-4-O active moiety.

Summary: The study investigates the activity of transition metals, metal-nitrogen-doped carbon catalysts, and supported phthalocyanine in the CO2 electroreduction to CO, and presents a unified mechanistic picture. It is found that MNCs have similar electron transfer properties to TMs in CO2 conversion, but can be limited by either CO2 star adsorption or proton-electron transfer reactions. The increased activity of MNC catalysts is attributed to the stabilization of larger adsorbate dipoles due to their discrete and narrow d states.

Summary: Despite the high Faraday efficiency for CO production, single-atom catalysts immobilized on nitrogen-doped carbon supports demonstrate low reaction current density. A novel amination strategy significantly increases the current density for CO production, particularly the aminated Ni single-atom catalyst achieving a remarkable CO partial current density of 450 mA cm(-2) with high FE. DFT calculations and experimental research reveal that the enhanced activity is due to the regulation of electronic structure of the aminated catalysts, offering a promising method for improving current density in industrial-level single-atom catalysts for CO2RR.
