Structural and hydriding/dehydriding properties of Mg–La–Ni-based composites

Rich magnesium ternary compound so-called LaCuMg8 derived from La2Mg17. Structure and hydrogenation behavior

“…Some other researches have already shown the existence of new ternary compounds in the system YeCueMg, LaeCueMg and TbeCueMg for example [5e7]. The new compound so-called LaCuMg 8 was brought to light but the same composition with Ni leads to a demixion into known ternary and binary compounds in agreement with previous studies on La 2 Mg 17 eNi composites [8]. In this paper, we report on its crystallographic properties and hydrogenation behavior.…”

Hydrogen storage properties of Mg–Ni–Fe composites prepared by hydriding combustion synthesis and mechanical milling

“…In our previous studies, we combined the process of HCS and MM, i.e., HCS + MM to prepare binary Mg-Ni and ternary Mg-La-Ni composites [46,47], finding that the hydrogen storage properties are improved remarkably as compared to the HCS product, suggesting that HCS + MM is promising to prepare advanced Mg-based hydrogen storage materials. However, it is not yet clear how about the effect of Fe on the hydrogen storage properties of Mg-Ni system prepared by the process of HCS + MM.…”

Hydrogen storage properties of LaMg2Ni prepared by induction melting

“…However, for Mg 2 Ni, it is difficult to get a desirable composition and single phase by conventional melt-cast methods, and the kinetics is still slow [10,11]. In order to improve the hydriding/dehydriding kinetics and plateau pressure performances for Mg 2 Ni, an approach of alloying with rare earths such as lanthanum has been attempted [12][13][14]. Thus, a new ternary magnesium-based compound, LaMg 2 Ni, was reported in recent years [15][16][17][18][19][20].…”
