Abstract

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. © 2014, Hydrogen Energy Publications, LLC.
