Resumen

This research contributes to the study of hydrogen storage of two Ti-Zr based systems using (I) titanium dioxide (TiO2) + zirconium acetylacetonate (C20H28O8Zr) and (II) titanium dioxide (TiO2) + zirconium tetrachloride (ZrCl4) as starting materials. Both systems were prepared by mechanical grinding under the same conditions, with composition of 50 wt.% Ti and Zr and milling time of 2, 5, 7, 15, 30 and 70 hrs. The samples were evaluated by hydrogen absorption tests and characterized by BET, XRD and TEM. The results of hydrogen storage at different pressures but same temperature showed that samples of the system I absorbed the largest quantities of hydrogen but difficult to release them, while the system II absorbed less amount of hydrogen but completely desorbed the absorbed hydrogen. The increase of the mechanical grinding time is directly associated with changes in hydrogen absorption capacity and formation of new components. The formation of oxide nanoparticles of Ti and Zr on the surface of TiO2 in samples from series II was associated with the hydrogen absorption capacity.
