| Popis: | Due to increase in environmental degradation, the careful monitoring of various hazardous gases and Volatile organic compounds become one of the chief topic of interest. One such hazardous VOC is Propan-2-ol which is a colorless, highly flammable compound with a strong odour. This compound have various applications but at the same time there are several health hazards associated with this compound. In this present work, the sensing of Propan-2-ol is done by using WO3–SnO2/Ag nanocomposite synthesized by solid state assisted hydrothermal method. The optical characterizations were done using UV/Vis and FTIR spectroscopy. The structural characterization was done using XRD technique. The morphological characterizations were done using FESEM and EDS technique. Electrical characterization were done from IV graphs. From these electrical characterizations the value of selectivity is calculated and the variation of response with time is studied. |
