Synthesis and hydrogen storage properties of core-shell structured binary Mg@Ti and ternary Mg@Ti@Ni composites

272Targeting the improvement in hydrogen sorption properties of ultrafine Mg powder, a ternary Mg@Ti@Ni composite powder with core-shell structure was systhesized. The dehydriding temperature of the hydrogenated ternary composite is lower than that of the binary composites and pure Mg due to the synergetic effects from Mg2Ni and TiH2 covered on Mg particles.
