Recent advances in MXene gas sensors: synthesis, composites, and mechanisms
Indexed incrossrefdoaj
Abstract
Abstract MXenes, a class of two-dimensional (2D) transition metal carbides and nitrides, have emerged as promising materials for high-performance gas sensors due to their unique combination of high electrical conductivity, tunable surface chemistry, and large specific surface area. This review highlights recent advances in MXene-based gas sensing materials, covering their synthesis strategies, structure–property relationships, and applications in both pristine and composite forms. We discuss conventional hydrofluoric acid etching and recent fluorine-free methods for MXene synthesis, and examine how these approaches affect surface terminations, interlayer spacing, and defect profiles relevant to gas sensing.…
