Title

Study of chemically synthesized MgMgH2 for hydrogen storage

Abstract

A detailed study was carried out to determine the basis for the improved characteristics of a MgMgH2 system that was previously reported by Bogdanovic and co-workers in this journal. The hydriding-dehydriding kinetics of this chemically synthesized system were investigated. A scanning electron microscope was used to examine the surface morphology of chemically hydrided samples. The surface of chemically prepared samples appeared to be covered with microspheroidal beads ranging in radius between 0.5 and 0.05 μm formed in a fractal-like configuration. Theoretical analysis indicates that the morphology of the chemically prepared samples could be responsible for rapid hydriding-dehydriding. The kinetic enhancement is believed to be partially due to the substantial increase in the surface area and partially due to the fast diffusion into the smaller particles. The effect of the addition of nickel to the surface was also investigated. © 1992.
