Strategy and Future Prospects to Develop Room-Temperature-Recoverable NO 2 Gas Sensor Based on Two-Dimensional Molybdenum Disulfide

Highlights MoS 2 shows enormous potential for gas sensing due to its high surface to volume ratio, position-dependent gas molecules adsorption and easy control on morphology. The recent experimental and theoretical strategies to develop NO 2 chemiresistance sensors based on MoS 2 are addressed. A detailed overview of the fabrication of MoS 2 chemiresistance sensors in terms of devices, structure, morphology, defects, heterostructures, metal doping, and under light illumination are discussed.
