Theoretical calculations indicate that, due to built-in electric field effects (BEFs), the plating/stripping mechanism shifts from [Zn(H₂O)₆]²⁺ to [Zn(H₂O)₅(SO₄)^2-]²⁺ without additional electrolyte additives, reducing the solvation ability of H₂O, enhancing the competitive coordination of SO₄²⁻, essentially eliminating the undesirable side effects of anodes.

Single-atom catalysts (SACs) have shown great potential because of their maximized atom utilization, but their limited stability and low metal loading restrict their performances. On the other hand, dual-atom catalysts (DACs) are atomic catalysts with two metal atoms nearby and offer enhanced electrocatalytic performances by aligning with the N ​≡ ​N bond to enhance N₂ reduction efficiency, potentially overcoming the limitations of SAC.
