- W2361805251 abstract "LaMg2Ni and Mg2Ni alloys were prepared by inductive melting under Ar atmosphere.X-ray diffraction(XRD) shows that during hydrogenation,LaMg2Ni alloy decomposes to LaH3 phase and Mg2NiH4 phase,in dehydriding process this alloy releases H2 and LaH3 phase changes to La3H7 phase.Compared with Mg2Ni alloy,on account of the existence of La hydride compound and phase transition from La3H7 phase to LaH3 phase in hydriding process,LaMg2Ni alloy shows better hydriding kinetics.It is within 280 s for LaMg2Ni alloy to reach 90% of the maximum hydrogen absorption capacity,while it needs 1 200 s for pristine Mg2Ni alloy to do so.The rate constant of LaMg2Ni alloy is larger than that of Mg2Ni alloy at the same temperature.La hydride compound is beneficial not only to the enhancement of hydriding kinetics but also to the improvement of the thermodynamic properties.The enthalpy and entropy for the hydriding Mg2Ni in the LaMg2Ni alloy are-53.02 kJ·mol-1,84.96 J· K-1·mol-1(H2),respectively.Mg2NiH4 in LaMg2Ni alloy is less stable than pristine Mg2Ni alloy(-64.50 kJ·mol-1 and-123.10 J·K-1·mol-1(H2)).Pressure-Composition-Temperature(P-C-T) measurement results show that the hydrogen storage capacity of LaMg2Ni alloy is about 1.95wt% and is kept stable from 603 K to 523 K,while the hydrogen storage capacity of pristine Mg2Ni alloy declines distinctly form 4.09wt% to 3.13wt% with the reduction of temperature from 603 K to 523 K.The hydrogen storage capacity of pristine Mg2Ni alloy at lower temperature(523 K) is only 76.5% when compared to that at 603 K,suggesting that La hydride compound could improve the hydriding/dehydriding properties of Mg2Ni alloy at low temperature." @default.
