Abstract

Abstract:

The LaMg_8.40Ni_2.34 alloy was prepared by vacuum induction melting and subsequent heating treatment. The phase structure, morphology, and hydrogen storage properties were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and pressure-composition-temperature (PCT) measurements. The LaMg_8.40Ni_2.34 alloy was composed of La₂Mg₁₇, LaMg₂Ni, and Mg₂Ni phases. The alloy can be activated in the first hydriding/dehydriding process. Its reversible hydrogen storage capacity was 3.01% (mass fraction) at 558 K. PCT curves showed two hydriding plateaus corresponding to the formation of MgH₂ and Mg₂NiH₄ and only one dehydriding plateau, which is due to the synergetic effect of hydrogen desorption between MgH₂ and Mg₂NiH₄. The activation energy values of LaMg_8.40Ni_2.34 alloy were (52.4±0.4) and (59.2±0.1) kJ·mol^-1 for the hydriding and dehydriding processes, respectively, and these were lower than that of the Mg₂Ni alloy. The LaMg_8.40Ni_2.34 alloy exhibited good activation behavior, hydrogen adsorption and desorption reversibility, and kinetic properties.
