Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 8 (Avril 2010) . - pp. 3539-3543 Titre : Highly sensitive and selective alcohol sensors based on ag-doped In2 O3 coating Type de document : texte imprimé Auteurs : Yidong Zhang, Auteur ; Zhi Zheng, Auteur ; Fengling Yang, Auteur Année de publication : 2010 Article en page(s) : pp. 3539-3543 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Alcohol Sensors Ag-Doped In2 O3 Coating Résumé : In this paper, we describe how to synthesize Ag-doped In2O3 nano particles and fabricate highly sensitive and selective alcohol sensors by solid-state reaction treatment from In(NO3)3·5H2O and AgNO3 mixtures at room temperature followed by calcination at 600 °C for 2 h. The samples were characterized by X-ray diffraction, scanning electronic microscopy, X-ray photoelectron spectroscopy. The diameter of the as-synthesized particle diameter is 80 nm under different dosage of Ag doping. In comparison with pure In2O3 sensor, all of the Ag-doped sensors showed better sensing performance in sensitivity, selectivity and optimum operating temperature. The effects of Ag content, alcohol vapor concentration, and operating temperature on the sensing characteristics of the Ag-doped In2O3 sensors were also investigated. We found that the Ag-doped sensor containing 10.0 mol % Ag exhibited the maximum sensitivity to alcohol vapor at 150 °C. A possible mechanism for the influence of Ag on the alcohol-sensing properties of Ag-doped In2O3 sensors was proposed.
