Abstract

High curvature carbon-supported isolated NiN₄ sites with ideal CO₂ reduction reaction performance were obtained through a top-down strategy. The charge polarization induced by the axial asymmetry of the carbon substrate can enhance the adsorption of COOH* and reduce the free energy barrier of the rate-determining step.
