The local structures of Ni single-atom catalysts were regulated by adjusting carbonization temperature of their precursors. The oxidation state, total coordination number, and bond length of the metal center decrease with the increase of the carbonization temperature. The relationship between structure and performance was explored. The structure after regulation could promote the adsorption of CO₂ and improve electrocatalytic CO₂ reduction activity.
