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

Covalent organic frameworks (COFs) are a class of intriguing materials with tunable electronic and optical properties. In this work, we investigate the properties COFs embedded hBN graphene. Our results demonstrate that graphene integration enhances ultraviolet visible light absorption C6N6 B6O6 monolayers, while charge transfer in all COF/graphene heterostructures leads to formation built-in electric field. Furthermore, show incorporating into enables control their bandgap through an applied field, resulting semiconductor-to-metal transition under moderate field strengths. Additionally, B6O6/hBN exhibits suitable band edge alignment for photocatalytic water splitting. These findings provide valuable insights COF potential applications optoelectronic devices. study contributes ongoing efforts design development novel 2D material future photonic applications.
