Interface and surface engineering of MXenes and COFs for energy storage and conversion

InfoMat, Journal Year: 2025, Volume and Issue: unknown

Published: March 11, 2025

Abstract MXenes, a class of two‐dimensional (2D) transition metal carbides, and covalent organic frameworks (COFs) deliver unique structural electrochemical properties, making them promising candidates for energy storage conversion applications. MXenes exhibit excellent conductivity tunable surface chemistries, whereas the COFs provide high porosity versatility. Recent advances in integrating MXene‐COF composites have revealed their potential to enhance charge transfer storage/conversion properties. The work highlights key developments integration, offering insights into applications batteries (Li‐ion, K‐ion, Na‐ion, Li‐S), supercapacitors, electrocatalysis (HER, OER, RR, NRR, ORRCO2), while also addressing current challenges future directions not only but other electronic devices. image

ConspectusOrganic/polymeric materials are promising as electrode for batteries because of their advantages flexibility, high specific capacity due to the possible multielectron transfer, low cost from green natural resources, and weak intermolecular interactions that enable storage low-cost large-sized or multivalent metal ions. However, development organic (OEMs) understanding electrochemical process face great challenges in characterization polymers charge mechanisms: (1) charged and/or discharged states OEMs often air unstable, which makes ex situ characterizations susceptible interference air. (2) OEMs, particularly polymeric materials, designed be insoluble deliver cyclability, it difficult them separated electrode. (3) Possible transfer determine whether proposed mechanism experiment results wrong when actual mismatches with theoretical based on mechanisms. (4) It is achieve single crystals polymers, hence, seems impossible know locations stored ions polymers. (5) The typical methods only qualitative, challenging quantify amount (6) Even most characterizations, they can give tendency qualitative structural evolution.In this Account, we an overview significance related mechanisms materials.
