| Résumé | Activated alloys synthesized by arc-melting were examined as catalysts for improving the hydrogen sorption characteristics of nanostructured magnesium hydride, proposed as a reversible hydrogen storage material. The MgH₂-catalyst absorbing materials were prepared by ball milling of pure MgH₂ with hydrided Zr₄₇Ni₅₃, Zr₉Ni₁₁, and other investigated alloys. The nanostructured MgH₂-intermetallic systems were tested at 250 ◦C and catalyst addition of eutectoid Zr₄₇Ni₅₃ resulted in the fastest desorption time and highest initial desorption rate. Also, the catalyzed Mg-hydride with activated Zr9Ni11 and Zr₇Ni₁₀ phases showed fast desorption kinetics. Moreover, the results demonstrated that the composition of dispersed ZrxNiy catalysts has a strong influence on the amount of accumulated hydrogen and desorption rate of Mg-nanocomposite. |
