Article Synopsis
- - The study focuses on creating efficient gas sensors using Quartz Crystal Microbalance (QCM) coated with Tungsten Oxide (WO) to detect harmful BTX compounds (Benzene, Toluene, and Xylene) in the environment.
- - Various scientific methods such as Optical Profilometry, Scanning Electron Microscopy, and X-ray Diffraction were used to analyze the sensor's surface and structure, revealing an optimal film thickness of about 200.81 nm with a granular microstructure.
- - The developed sensor demonstrated high sensitivity, with the best response to xylene (5.10 Hz/ppm), quick response times, and impressive repeatability (99%) and reproducibility (98%), making it a promising
