Abstract Electrochemical converting CO 2 to via single atom catalyst is an effective strategy for reducing concentration in the atmosphere and achieving a carbon‐neutral cycle. However, relatively low industrial processes large energy barriers activating severely obstruct actual application. Reasonably modulating coordination shell of active center enhance activity catalysts. Herein, well‐designed single‐atom electrocatalyst Ni‐N 3 S 1 developed large‐scale synthesis strategy. The constructed S‐C exhibits superior catalytic than 4 ‐C conversion H‐type cells, industrial‐level current density with excellent durability at wide pH range can be achieved gas‐diffusion flow cells. Experimental results functional theory (DFT) calculation demonstrate that introducing electronegative significantly regulate electronic structure site, promoting adsorption capacity decreasing barrier *COOH formation, thus larger size flexibility sulfur mitigate nickel agglomeration stability catalyst.

In the CO2 reduction reactions (CO2RR), product selectivity is strongly dependent on binding energy differences of key intermediates. Herein, we systematically evaluated CO2RR reaction pathways single transition metal atom doped catalysts TM1Cu/Cu2O by density functional theory (DFT) methods and found that *CO more likely to undergo C-O bond cleavage rather than be hydrogenated (TM = Sc, Ti, V, Cr, Mn, Fe, Co), which facilitates C2+ production with a low-energy pathway OC-C coupling, while it prefers form CHO Ni, Cu). The defects Cu in were confirmed enhance ethanol. Furthermore, established scaling relationship between free energies intermediates Bader charges active sites TM defective surfaces.
