摘要： The nanocomposite system for hydrogen storage is a composite of MgH2 powder with ZrNi5 powder and a combination of Nb2O5, TiC and VC. Preferably, the MgH2 is in nanocrystalline form and the ZrNi5 is significantly in a Friauf-Laves phase. The nanocomposite system is formed by combining the MgH2 powder with the ZrNi5, Nb2O5, TiC and VC, preferably in amounts of 4 wt. % ZrNi5+1 wt. % Nb2O5+0.5 wt. % TiC+0.5 wt. % VC, to form a mixture, and then performing reactive ball milling on the mixture. Preferably, the reactive ball milling is performed for a period of 50 hours.

摘要： The method for doping Mg with Ni includes cold-rolling the Mg material and then cold-spraying with Ni powder, and preferably further cold rolling the Ni-coated Mg to achieve the final Ni-doped Mg material. Preferably the Mg material is cold rolled for about 300 passes and the final Ni-doping concentration is about 5 wt. %.
