摘要：

The present paper reports a highly sensitive room temperature operable ethanol vapor sensor based on the electrical properties of nanostructured Pd-doped SnO2. Pd-doped SnO2 thin films were prepared on the glass substrate (1.2 cm(2)) using single-step thermal decomposition of stannous chloride (SnCl2) and palladium chloride (PdCl2). The resultant films were characterized by Scanning Electron Microscopy (SEM), X-ray diffraction spectroscopy (XRD), and UV-Vis spectroscopy. The doping of SnO2 with Pd was found to enhance the ethanol sensing response operating at room temperature. The 5% Pd-doped SnO2 sensor showed higher ethanol-sensing performance than the 0, 1, and 3% Pd-doped SnO2 with the sensing range of 10-190 ppm. The response and recovery time at 40 ppm of ethanol gas were similar to 107 s and similar to 378 s. The effect of Pd doping on the optical, structural properties of SnO2 and its ethanol vapor sensing behavior was studied and discussed. (C) 2019 Elsevier Ltd. All rights reserved.
