Notes:
Hydrogenation / dehydrogenation properties of a series of ternary face centered cubic(FCC) hydrides “Mg7MHx” (M = Sc, Ti, V, Zr, Nb, Hf and Ta), which were prepared by ahigh-pressure technique, were investigated. Differential scanning calorimeter (DSC) measurementsunder hydrogen atmosphere revealed that these hydrides exhibited reversible hydrogen releasing andre-storing properties at around 600 and 560 K, respectively. These releasing temperatures are lowerby 100 ~ 120 K than that of MgH2. Furthermore, pressure-composition isotherm at 523 K shows thatthese FCC hydrides release 3.8 - 5 wt. % hydrogens
