“…Acute poisoning may occur at concentrations of 40(ppm) of NH 3 gas, while high concentrations may lead to pulmonary edema (fluid buildup in the lungs) and permanent blindness. Therefore, it is imperative to devise a resolution for the problem of ammonia leakage through the implementation of effective ammonia sensors [1,2]. Currently, the predominant type of gas sensors utilized are semiconductor gas sensors fabricated from metal oxide or polymer materials.…”

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.
