In this work, three layers of SnO2/Pt/WO3 nanofilms with different WO3 thicknesses (50, 80, 140, and 260 nm) were fabricated using the sputtering technique. The WO3 top layer were used as a gas filter to further improve the selectivity of sensors. The effect of WO3 thickness on the (NH3, H2, and H2S) gas-sensing properties of the sensors was investigated. At the optimal WO3 thickness of 140 nm, the gas responses of SnO2/Pt/WO3 sensors toward NH3 and H2 gases were slightly lower than those of Pt/SnO2 sensor film, and the gas response of SnO2/Pt/WO3 sensor films to H2S gas was almost negligible. The calcification of NH3 and H2 gases was effectively conducted by machine learning algorithms. These evidences manifested that SnO2/Pt/WO3 sensor films are suitable for the actual NH3 detection of NH3 and H2S gases. 2021-07-05T07:41:55Z 2021-07-05T07:41:55Z 2021 Article https://www.sciencedirect.com/science/article/abs/pii/S0304389421001448?via%3Dihub https://dlib.phenikaa-uni.edu.vn/handle/PNK/1931 10.1016/j.jhazmat.2021.125181 en application/pdf Journal of Hazardous Materials
