Edge‐Rich Graphene Nanomesh Thermally Self‐Exfoliated From Metal‐Organic Frameworks for Boosting CO₂ Electroreduction

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 15, 2025

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.

Systematic X-ray absorption spectroscopy (XAS) photoelectron (XPS) analyses confirm atomic-level dispersion atoms their electronic interactions, which promote intrinsic activity. Zn/Sb-NC-g catalyst demonstrates superior (with half-wave potential reaching 0.905 V versus reversible hydrogen electrode), accelerated kinetics, excellent mass-transport property, significantly its microporous single-atom counterparts. When assembled into ZABs, delivers remarkable peak power densities up 209 426 mW cm-2 aqueous flexible batteries, respectively, favorable cycling stability over 1000 h at 10 mA cm-2.
