| Research Abstract |
Hydrogen (H) is considered to be the ultimate clean energy and an effective fuel to overcome the environmental problem. However, H gas has very small energy per volume and is desired to develop effective way to store H in a light material. Our goal is to prepare the H of whole Al bulk materials. Once the hydride is formed near surface of Al, H does not diffuse into the bulk and H stops the surface region. It is very important to facilitate H diffusion into the Al bulk before forming hydride. For this purpose, AlH3 is simulated by molecular dynamics. We also propose to use anodic coating of Al and change the bonding of H in Al. We prepared the samples at NIMS and experiments of hydrogenation under high pressure were performed at Spring8 (Dr. Saitoh). The hydrogenation takes place inside the Al bulk by anodic coating, and the amount of H storage is increased. We note that the anodic coating is a hopeful way to prepare bulk AlH3 materials.
