摘要：

In order to increase the hydrogen storage performance of Mg or MgH2-based materials, Li3N, LiBH4, Fe, and/or Ti were added. Mixtures with compositions of 50MgH(2)-50Li(3)N, 40Mg-10MgH(2)-50Li(3)N, 68MgH(2)-17LiBH(4)-15Fe, and 70MgH(2)-17LiBH(4)-13Ti were prepared by reactive mechanical grinding, and their hydrogen-storage properties were examined. 68MgH(2)-17LiBH(4)-15Fe and 70MgH(2)-17LiBH(4)-13Ti had higher hydriding rates than the Li3N-containing samples, 50MgH(2)-50Li(3)N and 40Mg-10MgH(2)-50Li(3)N, at 573 K under 12 bar H-2. However, the dehydriding rates of 68MgH(2)-17LiBH(4)-15Fe and 70MgH(2)-17LiBH(4)-13Ti were as low as those of the Li3N-containing samples at 573 K under 1.0 bar H-2.
