Abstract
Gas detection has become a popular research topic in the field of environmental protection and disease detection because of the concerning increase in environmental pollution and human health problems. 2D MXenes are promising candidates for room-temperature gas sensors because of their flexible and adjustable material compositions, high conductivities, high signal-to-noise ratios, and adjustable surface terminations. This paper presents the prospects of gas sensors, structure of MXenes, and potential sensing mechanisms of MXenes-based gas sensors. Applications of Ti3C2Tx, V2CTx, Nb2CTx, and Mo2CTx MXenes in gas sensors for the detection of different gases are reviewed, and the challenges and potential research directions for applying MXenes in gas sensors are discussed. This review provides ideas for designing novel sensitive materials by analyzing the potential value of MXenes-based gas sensors in the sensor field.
