Abstract Atomic‐level metal sites at the edges of graphene‐like carbon supports are considered more active for CO 2 electrocatalysis than those in‐plane. However, creating high‐density edge‐dominating sites, particularly in a simple, scalable, and self‐templated fashion, presents significant challenge. Herein, MOF‐mediated self‐exfoliation strategy is reported to preferentially integrate edge‐type FeN 4 onto ultrathin edge‐rich N‐doped graphene nanomesh (e‐Fe‐NGM). Theoretical calculations, finite element method (FEM) simulations, together with series situ spectro‐electrochemical experiments corroborate that can not only optimize electronic structure catalysts, facilitating formation * COOH desorption CO, but also effectively induce strong local electrostatic field, promoting interfacial H O supply thereby accelerating protonation process . Thus‐prepared e‐Fe‐NGM delivers remarkable Faraday efficiency (FE) above 98% over an ultra‐wide potential window 500 mV high turnover frequency 6648 h −1 , much superior controlled sample dominant plane‐type sites. Moreover, this self‐exfoliated, non‐catalyzed approach readily scalable be used produce large‐size industrial levels.

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.
