摘要
In this paper our work on lithium aluminium hydride doping with Ti（OBu）4 by mechanical milling was showed. Its thermodynamic and kinetics were enhanced greatly and its reversible hydrogen storage capacity could reach 3.0% （mass fraction）. From the X-ray diffraction （XRD） patterns, we found that a lot of LiAlH4 had been decomposed to Li3AlH6 and Al. The catalyst Ti（OBu）4 couldn’t be found after ball-milling, instead TiAl3 appeared. But the locations of Ti atoms are still not determined.
