چکیده انگلیسی
A sample of 86 wt% MgH2–10 wt% Ni–2 wt% NaAlH4–2 wt% Ti (named MgH2–10Ni–2NaAlH4–2Ti) was prepared by reactive mechanical grinding. Activation of the sample was not required at 573 K. At the first hydriding–dehydriding cycle (n = 1), the sample absorbed more than 5 wt% H at 573 K under 12 bar H2 for 60 min. The hydriding rate increased as the temperature increased from 423 K to 553 K. MgH2–10Ni–2NaAlH4–2Ti showed quite high hydridng rates at relatively low temperatures of 423 K and 473 K under 12 bar H2, absorbing 4.02 wt% H for 60 min at 473 K.
