The hydrogen storage properties of a destabilized / system ball-milled with , , and additives have been investigated. It is found that the system with additive has a lower dehydrogenation temperature than the ones with other additives. Further study shows that a higher amount of is more effective in reducing the desorption temperature of the / system, since it leads to a lower activation energy of dehydrogenation. The activations energies for mixtures containing 4, 10, and 25 mol% of are 141, 126, and 110 kJ/mol, respectively. However, the benefits of higher amounts of are offset by a larger reduction in hydrogen capacity of the mixtures.
