Abstract
Nanocomposites based on 2D materials exhibit synergistic behavior at their interfaces, making them a promising candidate for gas sensing applications. The MoS2/rGO nanocomposite used in this study was synthesized using a one-step hydrothermal process. By using X-ray diffraction (XRD), the synthesized composite was thoroughly characterized. The spin coater was used to deposit the nanomaterial thin film onto the glass substrate. The nanocomposite sensing was tested at a 40 ppm concentration of ammonia gas. An increase in ammonia concentration was found to correspond with a rise in the resistance of the sensor. The nanocomposite interface of this sensor enabled it to exhibit a synergistic behavior, resulting in several desirable characteristics, including low power consumption, fast response and recovery times, high selectivity, and a low operating temperature.
