Abstract
A hydrogen storage composite material having a Mg—Ni based alloy with a coating of a catalytically active metal deposited on at least a portion of a surface of said Mg—Ni based alloy. The coating is less than about 200 angstroms thick and preferably is formed from iron or palladium. The composite material is capable of adsorbing at least 3 weight percent hydrogen and desorbing at least 1 weight percent hydrogen at 30° C. The Mg—Ni based alloy has a microstructure including both a Mg-rich phase and a Ni-rich phase, micro-tubes having an inner core of Ni-rich material surrounded by a sheathing of Mg-rich material, amorphous structural regions and microcrystalline structural regions.
