Description
Summary:Design, synthesis and fabrication of novel p-n type semiconducting Pd incorporated MoO3: NiO (MNP) nanocomposite via Hydrothermal protocol and Impregnation method as Carbon-dioxide (CO2) gas sensing material was demonstrated with efficient conductivity and superior stability. The formation of nanocomposites MoO3:NiO and MoO3: NiO: Pd was systematically reviewed and confirmed by x-ray Diffraction (XRD) pattern, x-ray Flurescence Spectroscopy (XRF) and Transmission Electron Microscopy (TEM). A plausible gas sensing mechanism was deduced in terms of adsorption-desorption phenomenon, thus addressing the feasibility and potentiality of MNP nanocomposite engineered for the development of sensitive (S = 96%), selective and stable CO2 gas sensor.
