Experimental investigation and thermodynamic modeling of the phase equilibria at the Mg–Ni side in the La–Mg–Ni ternary system

Microstructure and electrochemical hydrogenation/dehydrogenation performance of melt-spun La-doped Mg2Ni alloys

“…With increasing La content, intermediate phases including Mg 17 La 2 [16,39], LaNi 2.28 [40,41] and La 2 Ni 3 [42] can be detected in the alloys with x = 0.1, 0.3 and 0.5, respectively. These newly formed intermediate phases can also be hydrogenated [41]. Along with the dominant Mg 2 Ni phase, multiphase systems have been proven to improve hydrogenation properties of Mg-Ni-La alloys [43].…”

“…For the analysis of microstructures and phase compositions resulting from various solidification paths of La-doped Mg 2 Ni alloys can be elaborated based on the Mg-Ni binary equilibrium phase [38] and Mg-NiLa ternary equilibrium phase diagrams [41] shown in Fig. 3.…”

Comparative investigation on feasible hydrolysis H 2 production behavior of commercial Mg‐M (M = Ni, Ce, and La) binary alloys modified by high‐energy ball milling—Feasible modification strategy for Mg‐based hydrogen producing alloys

“…The anodic reaction of the above‐mentioned hydrolysis process is M g → M g 2+ + 2e − , and the cathodic reaction is H 2 O + 2e − → H 2 ↑ + OH − . It is proved that the H 2 production reaction of Mg can be seriously prevented by the by‐product of Mg(OH) 2 passive film bonded on the surface of Mg surface 51‐54 . So, modifying the Mg‐based alloys to achieve rapid H 2 production and high conversion yield is the focus of research on hydrolysis hydrogen production Mg‐based alloys.…”
