ABSTRACT=<p>Transition metal dichalcogenides (TMDs) have been widely explored for their excellent gas sensing properties, especially high sensitivity and stability at room temperature. MoTe<sub>2</sub> exhibits good sensitivity and selectivity to some nitrogen-containing gases (i.e., NO<sub>2</sub>, NH<sub>3</sub>) 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<sub>2</sub>-based gas sensors with faster response and recovery speed. This paper summarizes the research progress of MoTe<sub>2</sub>-based gas sensing, focuses on the practical measures to improve the response and recovery speed of MoTe<sub>2</sub>-based sensors, and discusses the mechanism. This provides guidance for exploring higher performance MoTe<sub>2</sub> sensors.</p>
