Hydrogenation of Magnesium Titanium Multi- Layers — •Jara Kürschner, Helmut Uchida, and Astrid Pundt — Universität Göttingen, Institut für Materialphysik, Freidrich-Hund-Platz 1, 37077 Göttingen

Magnesium is a promising metal for hydrogen storage as it can store up to 7.6 weight% H. But, its hydrogen sorption kinetics are very slow. Magnesium can be combined with metals such as titanium, which have fast hydrogen sorption kinetics and do not alloy in equilibrium.

In this work, the hydrogen absorption properties of different magnesium titanium multi-layer stacks are investigated by electrochemical loading at room temperature. The palladium-capped samples are prepared by ion beam deposition on cleaned substrates and structurally analysed by X-ray diffraction.

Their properties such as hydrogen pressure and transmittance are analysed in dependance of the connection to the substrate and the Pd cap, the layer stacking, and the layer thickness.
