Hydrogenation behaviour, structure, morphology and dehydrogenation/re-hydrogenation performances of Mg-Pd nanocomposites prepared by high-energy reactive ball milling in H-2 (HRBM) of Mg in the presence of amorphous and crystalline Pd black (0.1-5 wt.%) were studied. Improvements of hydrogenation kinetics during HRBM were observed only for the materials prepared using crystalline Pd black. The obtained nanocomposites were characterised by modest improvements in their dehydrogenation and re-hydrogenation performances associated with the formation of Mg-Pd intermetallides.
