Abstract The synergistic effects in electrocatalysis can significantly enhance catalyst performance by improving catalytic activity, selectivity, and stability, optimizing reaction mechanisms electron transfer processes. This review summarizes recent advancements the of electrochemical reduction CO 2 (eCO RR) to multi‐carbon (C 2+ ) products. Starting with fundamental principles eCO RR for C product formation, paper outlines producing , 3 4 5 A comprehensive discussion is provided on critical impact structure–performance relationship production Subsequently, observed are classified various electrocatalysts different properties, including single/dual‐atom catalysts, multi‐centric single‐atom alloys, metal‐organic frameworks, heterojunction catalysts. Finally, challenges achieving selective formation through discussed, along corresponding strategies overcome obstacles.
