Abstract : Despite an increasing demand for applications, the partial selectivity of metal oxide-based gas sensors limits their practical use in some cases, such as for ethanol detection. Consequently, the search for performing ethanol gas is still an open challenge. In the present work, tungsten oxide was synthesized by the hydrothermal method. XRD analysis showed strong diffraction peaks for WO3 at 22.5s, 23.5° and 25° which corresponds to (111), (110) and (022) planes with the crystallite size of 8.30 nm, 12.30 nm and 16.08 nm, respectively. EDAX results showed that the atomic percentage of synthesized nanoparticles is 25.68% and 74.32% of W and C, respectively. The synthesized WO3 nanomaterials were fabricated pallets for highly sensitive detection of ethanol gas. Finally, optimization is carried out in different ppm concentrations for WO3 nanomaterials to ensure it following the linear characteristics of gas sensor. The response time at 50 ppm,75 ppm and 100 ppm is 85.54 s, 294.08 s, 189.78 s, and the relaxing time is 446.33 s, 254 s, 220 s, respectively. Sensitivity of 6.06% was observed.
