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

Published: Jan. 17, 2025

The MXene, which is usually transition metal carbide, nitride, and carbonitride, one of the emerging family 2D materials, exhibiting considerable potential across various research areas. Despite theoretical versatility, practical application MXene prohibited due to its spontaneous oxidative degradation. This review meticulously discusses factors influencing oxidation MXenes, considering both thermodynamic kinetic point view. mechanisms are systematically introduced, based on experimental models. Typically, surfaces edges MXenes susceptible oxidation, as surface terminal groups easily attacked by oxygen water molecules, ultimately leading structural deformation. To retard degradation, ligand mediated surface/edge passivation suggested a promising strategy. In this regard, detailed strategies for explained types chemistry at MXene-ligand interface-covalent bonding, electrostatic interactions, hydrogen bonding-and type stabilizing moieties-organic, inorganic, biomolecules, polymers. retardation discussed in relation with interaction passivating moiety. aims catalyze future identify efficient cost-effective ligands engineering enhancing their stability.
