Fig. 10. (a) Hydrogenation kinetics behavior measured at 200 °C under 10 bar of H₂ for MgH₂/x MG-Zr₂Pd powders (x; 2.5, 5, and 10 wt%) after RBMed for 50 h, and (b) as-hot pressed nanocomposite MgH₂/5 MG-Zr₂Pd button measured at different temperatures (50, 100, 150, 175, and 200 °C) under 10 bar of H₂. The hydrogenation kinetics measured at 200 °C/10 bar H₂ for pure MgH₂ obtained after 50 h of RBM and then consolidated at 350 °C is shown in (b).
