Comparative investigations on the hydrogenation characteristics and hydrogen storage kinetics of melt-spun Mg10NiR (R = La, Nd and Sm) alloys

Hydrogen storage properties of Mg–Ce–Ni nanocomposite induced from amorphous precursor with the highest Mg content

“…Because the hydrogen storage kinetics is not much influenced by different REH x for meltspun MgeREeNi alloys [19]. Our present work can also be reference for design of other MgeREeNi hydrogen storage alloys.…”

“…It should be pointed out that the in situ formation of nanocrystalline REH x and Mg 2 Ni (or Mg 2 NiH 4 ) particles are important for abovementioned enhancement in MgeREeNi system. From literatures [14,19,22] and our previous work [17], the more homogeneous precursor, the better hydrogen storage properties, and thus amorphous structure is the most expected.…”

High glass forming ability correlated with microstructure and hydrogen storage properties of a Mg–Cu–Ag–Y glass

“…The proper addition of rear earth (Y, La, Ce) to Mg and Mg-Ni alloys by the RQ technique facilitates even more disordered systems, i.e. partially crystalline [13][14] or monolithic amorphous alloys [15][16][17][18] with further improved storage properties.…”

An investigation on hydrogen storage thermodynamics and kinetics of Nd–Mg–Ni-based alloys synthesized by mechanical milling

“…Wang et al [22] investigated the electrochemical hydrogen storage properties of ball-milled MmMg 12 alloy with Ni powders, and the results indicated that as the Ni content in the alloy increased from 150 to 200 wt.%, the first discharge capacity of the ballmilled sample increased from 770 to 1200 mAh/g. Zhang et al [23] reported that the as-spun Mg 10 NiR (R ¼ La, Nd and Sm) alloys displayed superior hydriding and dehydriding kinetics as a result of adding different rare earth elements. Yartys et al [24] reported that the LaMg 11 Ni alloy solidified at the highest cooling rate exhibited the fastest hydrogenation kinetics, reaching maximum hydrogenation capacity of 5.02 wt.% H.…”
