Synthesis and hydrogen storing properties of nanostructured ternary Mg–Ni–Co compounds

The homogeneous Mg 2 Ni 1 - x Co x ( x = 0.05 , 0.1) compounds were successfully prepared from magnesium, nickel and cobalt ultrafine particles, which were obtained from a hydrogen plasma–metal reaction. XRD and TEM results demonstrate that the homogeneous nanostructured Mg 2 Ni 1 - x Co x with less impurity were successfully synthesized by this method. DSC in hydrogen atmosphere, pressure–composition isotherm and the kinetics of hydrogen adsorption/desorption were investigated. The results show that the nanostructured Mg 2 Ni 1 - x Co x compounds present superior sorption kinetics.
