► High-energy reactive ball milling in H2 of Mg with amorphous and crystalline Pd black. ► Only crystalline Pd black improves hydrogenation/dehydrogenation performances. ► The modest improvements are associated with the formation of Mg–Pd intermetallides. Hydrogenation behaviour, structure, morpholo...
