摘要

Synchrotron based in situ x-ray diffraction measurements and an analysis of the dehydrogenation of MgH₂ and MgH₂ with Ti-based additives, including TiH₂ and TiMn₂, are presented. γ-MgH₂ to β-MgH₂ phase transformation in ball milled MgH₂ samples was observed prior to the dehydrogenation reaction. During the dehydrogenation of MgH₂ there were no significant phase transformations observed of the additives. These Ti-based additives functioned as catalysts during the dehydrogenation process resulting in lower temperature of dehydrogenation.
