Recent advances and prospects on MoX2 (X=S, Se, Te) nanostructure-based sensors for room temperature gas detection: A review

The development of molybdenum dichalcogenides MoX2 (X = S, Se, Te) two-dimensional (2D) nanostructures for room-temperature gas sensing has drawn intense interest in recent years. Nevertheless, low sensitivity, timeconsuming recovery process, and incomplete recovery have hindered their widespread application. Substantial effort has been dedicated to creating specialized gas sensors having enhanced sensing capabilities. This review highlights the relevant studies in this area, with particular emphasis on the material properties, synthesis approaches, and strategies for enhancing the effectiveness of gas sensors operating at room temperature, as well as challenges encountered in this area. Finally, potential directions for developing these nanostructures as efficient sensors are discussed.
