Ti-doped Li3AIH6 with nanometer-scale crystallites has been prepared for the first time by high-energy ball milling technique. The small crystallite sizes of about 40 nm result directly from the mechanic-chemical pathway and the dispersion of a nanophase. The dehydriding/hydriding is apparently controlled by a rapid phase-separation induced by the Ti(0)/Ti(3+)/Ti(4+) defect sites that are favorable for the catalysis of dehydrogenation/hydrogenation. Such Ti-doped nanocrystals are of interest for a broad range of applications in areas such as direct hydrogen fuel cell vehicles not only due to their high hydrogen capacity but also for their reversible hydrogen storage.
