Abstract

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 MoS2 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 MoS2 research in gas sensing applications is provided. The synthesis of some exciting different nanostructures and hybrids of the MoS2 on a rigid as well as flexible substrate is summarized, as they play an important role in tuning the gas sensing characteristic of the MoS2 . The gas sensing performance of the MoS2 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 MoS2 on the emerging flexible gas sensing platform are also highlighted. Finally, some insights into new challenges and future perspectives in the promising MoS2 research for gas sensing applications are presented.
