One such promising application of TMDs capitalizes on their sensitivity to surface interactions and low chemical reactivity is gas sensing. Thanks to their exceptional surface-to-volume ratio, TMDs hold the potential for robust responses, even at room temperature (RT), provided that the per-molecule transfer rates are sufficiently high for the target analyte. As a result, materials such as MoS 2 , MoSe 2 , and MoTe 2 have exhibited remarkable sensitivity to NO 2 , facilitating excellent detection limits even under RT conditions . Moreover, the physisorptive nature of adsorption interactions on TMDs allows for quicker sensor recovery at lower temperatures compared to conventional metal-oxidesemiconductor (MOS) sensors, thereby supporting reduced operating temperatures. This collective set of advantages has fueled extensive research into gas sensors based on TMDs.
