Abstract

Inorganic materials play a significant task in the improvement of chemiresistive gas sensors. We have prepared tungsten oxide (WO3) by hydrothermal method at 150 °C and it has been used for gas sensing applications. The prepared sensor film was characterized by X-ray diffraction (XRD), Raman Spectroscopy, X-ray photoelectron spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) and contact angle. Developed tungsten oxide (WO3) sensor film works excellently at 200 °C operating temperature and shows a higher response to NO2 gas. The chemiresistive metal oxide based sensor is extremely sensitive, steady, and reproducible also has squat response-recovery time.
