AbstractDifferent from conventional method, we have produced nanoparticles of Mg, Fe, Co, Ni, Cu and other metals by hydrogen plasma metal reaction (HPMR) in semi-industrial scale. Using these elemental nanoparticles as raw materials, nanostructured Mg-based compounds with high purity including MgNi, MgCo, MgCu and MgFeH are further synthesized by gas-solid reaction in much mild conditions. The MgNi nanoparticles of 50 nm can be prepared at 523 K under 4 MPa H. The formation mechanisms of the elemental nanoparticles during HPMR and the nanostructured Mg-based compounds during gas-solid reaction are discussed. The nanostructure of these samples greatly enhances the kinetic properties of hydrogen absorption and desorption. The MgNi nanoparticles can absorb hydrogen and saturate at 0.95 H M (the number of hydrogen atoms per metal atom) in several minutes at 493 K. The sorption kinetics of the nanostructured MgNi is almost stable during ten cycles. The thermodynamic properties of these nanostructured MgM are improved slightly. © 2012 Elsevier B.V.
