Abstract Multi‐metallic catalysts with specific structures play a crucial role in enhancing the selectivity and activity of chemical reactions. However, challenges such as unfavorable alcohol adsorption on catalysts, CO poisoning, high free energy barriers during oxidation processes pose significant obstacles to catalysts' ability cleave C─C bonds for complete oxidation. Here, series PdCuCo metalene electrocatalysts is reported, wherein varying intermetallic interactions among Pd, Cu, Co effectively modulate pathway. Notably, catalyst Pd 0.15 Cu 0.35 2 , synthesized by galvanic replacement metallic surface, delivers remarkably electrocatalytic ethylene glycol glycerol alkaline electrolytes (9.7 10.9 A mg −1 respectively), both which are much better than reported broadly applicable various alcohols. High performance assigned structural advantages material synergistic effects multiple metals. This synergy not merely enhances surface electronics, fostering creation exclusive active sites, but also facilitates oxidative cleavage stable bond efficient
