The redox cycle of iron oxides (Fe3O4 + 4H2 ↔ 3Fe + 4H2O) which can be applied as a new method of storage and supply of hydrogen were studied. The iron oxides were prepared by precipitation of aqueous ferric nitrate. The addition of aluminium oxide into iron oxides prevented the sintering of metal iron and/or iron oxides during repeated redox cycles. The optimal calcination temperature for cylindrical pellets preparation was found to be 850 oC. Transport parameters for Fe2O3/Al2O3 and Fe/Al2O3 samples, which can be utilized for optimization of porous structure prepared pellets, were determined by the inverse gas chromatography.
