摘要
Scanning electron microscopy and X-ray diffraction are used to study the morphology of particles of oxygen-stabilized Ti4Fe2Ox (x = 0.5 and 1.0) powder and the lattice parameters of these compounds Hydrogen absorption during the first hydrogenation-dehydrogenation cycles is investigated The time characteristics of hydrogen absorption and the reversible hydrogenation capacity are determined. The correlation between absorption and structural characteristics is established. This correlation is sensitive to the oxygen content in the compound.
