Interface and surface engineering of <scp>MXenes</scp> and <scp>COFs</scp> for energy storage and conversion

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