内容記述 | Temperature dependence of hydrogen permeation rate was examined for a vanadium membrane oxidized at room temperature by exposure to air. Pressure dependence of the permeation rate was also examined to determine the rate-controlling process of the permeation. The change in the chemical state of surface oxide by heating in vacuum was analyzed by X-ray photoelectron spectroscopy (XPS). The permeation rate was small below 300℃ and significantly increased in the temperature range from 300 to 400℃. The rate-controlling process of the permeation was determined as surface reaction because the permeation rate increased in proportion to the upstream pressure. A surface oxide film consisting of V2O3 and VO was formed on the vanadium surface. At almost the same temperature at which the permeation rate increased, V2O3 and VO were reduced to metal. Hence, the increase in permeation rate at a temperature above 300℃ was ascribed to the reduction of V2O3 and VO to metal. The reduction of V2O3 to metal took place via VO. | |||||
