Hydrogen storage properties of nonstoichiometry La_((2-x))Ti_xMg(NiCo)_(9.5)(x=0.0-0.5) alloys
【摘要】:正La_((2-x))Ti_xMg(NiCo)_(9.5)(x=0.0-0.5) alloys were prepared and the effect of partial substitution of Ti for La on the hydrogen storage properties of nonstoichiometry La_((2-x))Ti_xMg(NiCo)_(9.5)(x=0.0-0.5) quinary alloys were investigated.XRD measurements showed that all alloys were consisted of a main phase with hexagonal PuNi_3-type structure and a few impurity phases(mainly LaNi_5 phase).The hydrogen absorption/desorption
