Abstract In gas sensor technology, current research efforts are focused on developing a high performance miniaturized gas sensor operating at room temperature. In recent years, layered semiconducting material MoS 2 has gained vast attention in sensing field owing to the detection of a variety of analytes at room temperature, high surface‐to‐volume ratio, and also provided substantial advantages in emerging flexible and wearable sensing field. Herein, a state‐of‐art overview of the utilization of burgeoning MoS 2 research in gas sensing applications is provided. The synthesis of some exciting different nanostructures and hybrids of the MoS 2 on a rigid as well as flexible substrate is summarized, as they play an important role in tuning the gas sensing characteristic of the MoS 2 . The gas sensing performance of the MoS 2 sensors with proposed mechanisms is discussed in the context of a wide range of different morphologies/nanostructures, nanocomposites, van der Waals heterostructures, and photoactivation effects. Moreover, rapid advances and growing significance of the MoS 2 on the emerging flexible gas sensing platform are also highlighted. Finally, some insights into new challenges and future perspectives in the promising MoS 2 research for gas sensing applications are presented.
