| Abstract | A ternary hydride, the face-centered cubic (FCC) type Mg7TiH16, synthesized under 8 GPa hydrogen pressure (HP) exhibited a reversible hydrogenation and dehydrogenation property around 600K on the differential scanning calorimeter (DSC) measure ments. The FCC phase was decomposed during hydrogen releasing and restoring cycles. After the hydrogen restored process, the XRD pattern consisted of MgH2, TiH2 and Mg peaks. Meanwhile, a mechanically-alloyed (MA) 7MgH2+TiH2 sample exhibited similar hydrogen storage properties to the HP sample. Based on a structural analysis using the synchrotron XRD data, it was shown that the phase abundance for the HP sample is equivalent to the one for the MA sample. |
