چکیده انگلیسی
Samples of Mg-10Â wt.%Fe2O3 using nano-structured Fe2O3 synthesized by spray conversion were prepared by mechanical grinding under H2 (reactive mechanical grinding) under the optimum conditions for the preparation of the sample Mg-10Â wt.%Fe2O3 using purchased Fe2O3. The sample Mg-10Â wt.%Fe2O3 as milled absorbed 3.87Â wt.% hydrogen at 593Â K under 12Â bar H2 for 60Â min. Its activation was accomplished after two hydriding-dehydriding cycles. The activated sample absorbed 5.55Â wt.% hydrogen at 593Â K, 12Â bar H2 for 60Â min. Hydrogen-storage capacity is 6.67Â wt.% under 12Â bar H2 at 593Â K (from P-C-T curve). The effects of reactive mechanical grinding and hydriding-dehydriding cycling on the hydrogen properties of Mg were discussed.
