Abstract

In the present study we describe the design, fabrication and gas sensing performance of p-NiO/n-MoO3 (MN) nanocomposites functionalized by noble metal Pt (MNP). The formation of the nanocomposite was systematically reviewed and confirmed by X-Ray Fluorescence Spectroscopy (XRF) and X-Ray Diffraction (XRD) pattern. The MN nanocomposite impregnated with noble metal - Pt (MNP) showed better efficiency of S=92% towards Carbon dioxide (CO2) gas compared to MN (S=80) and selectivity towards CO2 in comparison to other interfering gases i.e., H2, EtOH, MeOH, NH3 and LPG, with superior stability.
