“…The apparent activation energy of ball-milled MgH 2 −LiAlH 4 sample is calculated to be 101. 5 wt % hydrogen is absorbed within 300 s. However, a hydrogen absorption capacity of 3.64 wt % is reached within 300 s for the MgH 2 −LiAlH 4 + 5 mol % MnFe 2 O 4 sample, which is higher than that of MgH 2 −LiAlH 4 sample and TiF 3 -doped sample in other report. 35 These results demonstrate that the MnFe 2 O 4 nanoparticles catalyst also remarkably improves the rehydrogenation kinetics performance of the MgH 2 −LiAlH 4 sample.…”

“…Experimentally, it has been shown that the ball-milling with a small amount of transition metals (TM) or their oxides drastically accelerate the hydrogen kinetics. Moreover, they reduce the decomposition temperature of the hydride [4,5,8,9]. In recent experiment, it was shown that adding MnFe 2 O 4 nanoparticles improve considerably the thermodynamic dehydrogenation properties of ball-milled MgH 2 doped with 7 mol% MnFe 2 O 4 [10].…”

“…Однако литературные данные по влиянию МА магния на его водородаккумулирующие свойства неоднозначны. Было установлено, что предварительное сухое механи-ческое сплавление гидрида магния с графитом улучшает кинетику дегидрирования [15], что связывается авторами со снижением размеров частиц композита. В работе [16] наблюдалось увеличение скорости гидрирования после предварительной МА магния с активированным углем и углеродными нанотрубками, а в работе [17] получен противоположный результат.…”
