چکیده انگلیسی
The effect of Cu-doping on the hydrogen storage properties of Mg95Ni5Cux (x = 0, 0.5, 1, 2) prepared by hydriding combustion synthesis and mechanical milling (HCS + MM) was studied. For dehydriding properties, the dehydriding temperature onset decreases from 450 K for Mg95Ni5 to 420 K for Mg95Ni5Cu2. Additionally, the activation energy for dehydriding decreases from 116 kJ/mol for Mg95Ni5 to 98 kJ/mol for Mg95Ni5Cu2, indicating that the dehydriding reaction is activated by the catalytic effect of Cu. Moreover, the hydrogen absorption capacity of Mg95Ni5Cu2 at 373 K in 100 s increases from 0.95 to 4.16 wt.% by MM pretreatment before HCS. The factors for the improvement of the hydrogen storage properties are discussed in this paper.
