Gas Sensing Properties of Ordered Mesoporous SnO2
We report on the synthesis and CO gas-sensing properties of mesoporous tin(IV) oxides (SnO2). For the synthesis cetyltrimethylammonium bromide (CTABr) was used as a structure-directing agent; the resulting SnO2 powders were applied as films to commercially available sensor substrates by drop coating. Nitrogen physisorption shows specific surface areas up to 160 m·g and mean pore diameters of ab...
متن کاملPolyethylene glycol-directed SnO2 nanowires for enhanced gas-sensing properties.
SnO(2) nanowires with lengths in the tens of micrometres range have been synthesized on a large scale via a facile polyethylene glycol-directed method at ambient temperature followed by a suitable thermal treatment of the precursor nanowires. The morphology of the precursor of the SnO(2) nanowires is tunable by changing the concentration of either SnCl(2) or polyethylene glycol. After calcinati...
متن کاملSynthesis of SnO2 Nanowires their Structural and H2 Gas Sensing Properties
SnO2 nanowires were prepared on bare oxidized silicon, Au and SnO2 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 SnO2 nanowires. FE-SEM images indicated that the size of SnO2 nanowires depend on the type of substrate. Gas sensor was fabricated by ...
متن کاملSynthesis and Ethanol Sensitivities of Sn02 nanowires Suvit
Sn02 nanowires with diameters of 30 — 200 nm have been synthesized by using carbothermalprocess via a thick film of tin dioxide and carbon powder precursor. The nanowires werecharacterized by X-ray power diffraction (XRD), scanning electron microscopy (SEM),transmission electron microscopy (TEM) and Selected Area Electron Diffraction (SAED).The gas sensing characteristic of nanowires toward eth...
متن کاملSensing of Methanol and Ethanol with Nano-Structured SnO2 (110) in Gas Phase: Monte Carlo Simulation
The SnO2 films deposited from inorganic precursors via sol–gel dip coating method have been found to be highly sensitive to methanol and ethanol vapor. Three dimensional nano-structure materials have attracted the attention of many researches because the possibility to apply them for near future devices in sensors, catalysis and energy related. The sensitivity and selectivity of SnO2 (110) nano...
