摘要: Abstract NaMgH 3 hydride with perovskite structure has been synthesized by high-energy ball milling, the maximum hydrogen-desorbed amount of which is 3.42 wt.% at 638 K. Two decomposition steps have detected for perovskite-type hydride, calculated values activation energy two are 180.25 ± 8.25 kJ/mol and 156.23 ± 18.54 kJ/mol Kissinger method. In comparison Li 0.5 Na MgH better dehydriding kinetic properties higher (4.11 wt.%) due to partial replacement Li. LiMgH cannot be milling mixture LiH 2 hydrides. However, this milled 5.54 wt.% 638 K, may suggest that a good catalyst dehydrogenation , but further research needed.
