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.
