Synthesis and room temperature CH4 gas sensing properties of vanadium dioxide nanorods
چکیده انگلیسی
Vanadium dioxide nanorods with monoclinic crystalline symmetry were grown directly on the commercial ceramic substrate through thermal evaporating vanadium pentoxide powder in a tube furnace. The morphology and crystal structure of as-grown products were characterized by field emission scanning electron microscope and X-ray diffraction respectively. The results showed that the morphology of products could be affected by deposition pressure. Moreover, gas-sensing properties of VO2 nanorods sensors were carried out versus different concentration of methane at room temperature. It was found that the sensor based on VO2 nanorods exhibited a good performance to CH4. This was owing to the special nanorods structure of VO2 material, which providing a large specific surface area. VO2 nanorods efficiently enhanced CH4 gas-sensing performance which provides VO2 a promising semiconductor metal oxide material for application in CH4 sensor.
