Two-Dimensional Materials-Based Gas Sensors: Materials, Mechanisms, Performance and Future Directions
Abstract: Two-dimensional (2D) materials are emerging candidates for next-generation gas sensors. These materials attracted pronounced attention for gas sensing applications due to their atomic-scale thickness, high surface area, and tunable electronic properties. Among 2D materials such as graphene, transition metal dichalcogenides (TMDs), MXenes, and black phosphorus enable effective gas adsorption and charge transfer, allowing sensitive and low-power detection at room temperature. This review concisely summarizes the fundamental gas sensing mechanisms in 2D materials, including chemiresistive behavior and carrier modulation, and compares recent sensor performances in terms of sensitivity, selectivity, and detection limits. Current challenges and future prospects, including defect engineering and advanced sensor architectures, are also addressed.
