| Abstract: | Mg2Ni alloys have been synthesized through the solid state diffusion method. The effect of substitutions of Cr for Ni and Ti for Mg on hydrogen storage properties was studied. In the case of Mg2Ni0.8Cr0.2, Mg1.8Ti0.2Ni0.8Cr0.2, the desorption pressure increased after the substitutions of Cr for Ni and Ti for Mg. The hydrogenation properties of Mg2Ni can be improved by tailoring the effect of cell volume using Cr and Ti elements. |
