摘要:	Metal alloys such as Mg2Ni and TiFe can absorb and store H-2 to form metal hydrides. The alloys are frequently prepared by grinding the metal ingredients together. In this work, a solvothermal synthesis was taken to prepare the Mg-Ni/C nanocomposite from vitamin C, magnesium acetate, and nickel acetate, using ethylene glycol as solvent and reductant. Without adding Pd as nucleating agent, it is proposed to obtain Mg-Ni alloys by reduction and carbon nanoparticles by carbonization. XRD analysis shows that Mg2Ni and Mg-Ni-2 have been formed as nanocomposite with carbon. After calcination in vacuum at 500 degrees C for 1 h, the Mg-Ni/C nanocomposite showed enhanced magnetism. XRD results give peaks of Ni and MgO, indicative of phase separation and Mg oxidation. In conclusion, it is feasible to synthesize Mg-Ni/C or other carbon-containing hydrogen storage composites using the solvothermal method. Copyright (C) 2012, Hydrogen Energy Publications, LLC.
