| Abstract | (MgH2+ Y, Ce) mixtures were processed by mechanical milling in an attempt to improve the hydrogen sorption properties of MgH2. The structural evolution and hydrogen desorption properties were investigated by a range of experimental techniques. XRD analysis shows the formation of a stable hydride phase, CeH2.35or YH3, in the relevant mixture during milling. Hydrogen desorption of the milled mixtures was characterised by coupled thermogravimetry (TG) and differential scanning calorimetry (DSC). Milled (MgH2+ Ce) samples show higher desorption kinetics than the (MgH2+ Y). The formation of CeO2in the (MgH2+ Ce) mixture benefits the desorption kinetics, likely due to the formation of surface defects on MgH2and surface catalysis by the oxide. © 2006 International Association for Hydrogen Energy. |
