Transition metal dichalcogenides (TMDs) have been widely explored for their excellent gas sensing properties, especially high sensitivity and stability at room temperature. MoTe exhibits good sensitivity and selectivity to some nitrogen-containing gases (i.e., NO, NH) and has received extensive attention in gas sensing. In addition, increasingly complex production environments place demands on high-quality gas sensors. Therefore, worldwide efforts are devoted to designing and manufacturing MoTe-based gas sensors with faster response and recovery speed. This paper summarizes the research progress of MoTe-based gas sensing, focuses on the practical measures to improve the response and recovery speed of MoTe-based sensors, and discusses the mechanism. This provides guidance for exploring higher performance MoTe sensors.
过渡金属二硫属化物（TMDs）因其优异的气敏性能，特别是在室温下的高灵敏度和稳定性，而受到广泛研究。碲化钼（MoTe）对某些含氮气体（如一氧化氮、氨气）表现出良好的灵敏度和选择性，在气体传感领域受到了广泛关注。此外，日益复杂的生产环境对高质量气体传感器提出了要求。因此，全球都在致力于设计和制造具有更快响应和恢复速度的基于MoTe的气体传感器。本文综述了基于MoTe的气敏传感研究进展，重点关注提高基于MoTe的传感器响应和恢复速度的实际措施，并探讨其机理。这为探索更高性能的MoTe传感器提供了指导。
