Synthesis of SnO2 nanowires their structural and H2 gas sensing properties
Source abstract
Abstract
Abstract SnO 2 nanowires were prepared on bare oxidized silicon, Au and SnO 2 -coated substrates by thermal evaporation of tin grains in argon atmosphere at 900 °C. X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM) were used to characterize the SnO 2 nanowires. FE-SEM images indicated that the size of SnO 2 nanowires depend on the type of substrate. Gas sensor was fabricated by dispersing SnO 2 nanowires on an interdigitated Pt-electrode. H 2 gas sensing properties of these sensors made of nanowires prepared on three different substrates were measured at various operating temperatures and concentrations respectively. SnO 2 nanowires deposited on Au-coated substrates showed the highest sensitivity of 11.5 at 100 °C upon exposure to H 2 gas of 1000 ppm.
