Heterojunction Light illumination MoS2 NO2 gas sensors.Ī Schematic structure of 2H-MoS 2. Understanding and addressing these issues are expected to yield the development of highly reliable and industry standard chemiresistance NO 2 gas sensors for environmental monitoring. Finally, the review concludes the challenges and future perspectives to further enhance the gas-sensing performance of MoS 2. Moreover, the experimental and theoretical aspects used in designing MoS 2-based NO 2 sensors are also discussed extensively. The aim of this review is to provide a detailed overview of the fabrication of MoS 2 chemiresistance sensors in terms of devices (resistor and transistor), layer thickness, morphology control, defect tailoring, heterostructure, metal nanoparticle doping, and through light illumination. MoS 2 has a large surface area for NO 2 molecules adsorption with controllable morphologies, facile integration with other materials and compatibility with internet of things (IoT) devices. Molybdenum disulfide (MoS 2) has emerged as a potential candidate for developing next-generation NO 2 gas sensors. These limitations of traditional materials are forcing the scientific community to discover future alternative NO 2 sensitive materials. The NO 2 sensors based on traditional materials have limitations of high-temperature requirements, slow recovery, and performance degradation under harsh environmental conditions. Nitrogen dioxide (NO 2), a hazardous gas with acidic nature, is continuously being liberated in the atmosphere due to human activity. ![]()
