Description
Coal mine gas explosions represent one of the most catastrophic hazards in underground mining, ranking among the leading causes of mining fatalities worldwide and imposing severe economic burdens on coal-generating nations. Therefore, the detection of these volatile organic compounds (VOC) gases in the early stages is very significant for preventing catastrophic explosions in underground coal mines. Two-dimensional (2D) nickel oxide – tungsten sulfide (NiO-WS2) heterostructured nanomaterials were prepared through the hydrothermal method using a pressure reactor, and consequently, the sensors were fabricated from these nanomaterials. X-ray powder diffraction (XRPD) confirmed the crystal structure. Scanning electron microscopy (SEM) confirmed the particle morphology. Elemental composition and mapping were analysed through energy dispersive X-ray spectroscopy (EDS). The specific surface area and pore distribution were confirmed by the Brunauer-Emmett-Teller (BET) technique. Photoluminescence analysis was carried out to explore the intrinsic defects within the heterostructures. VOC vapours were exposed towards the fabricated sensors in order to investigate the sensing analysis.
