چکیده انگلیسی
As reported previously, MgH2 synthesized by hydriding chemical vapor deposition (HCVD) was made of single crystals with nano-fibrous figures. Therefore, the hydrogen storage property of the HCVDed MgH2 is expected to reflect its structural character. In this study, we examined the hydrogen storage property of MgH2 synthesized by HCVD. Results of pressure-composition-isotherm (PCT) measurement showed that the HCVDed MgH2 reversibly absorbed and desorbed hydrogen as much as 7.6 mass% without any activation treatment retaining the fiber shape. Each hydrogenation/dehydrogenation rate was great because hydrogen diffused through a short pathway in a radial direction of the fiber.
