摘要	Al(3)Ti was directly utilized as catalyst precursor to examine its catalytic activity in the reversible dehydrogenation of NaAlH(4). It was observed that Al(3)Ti possessed considerable catalytic effect on the de-/hydriding reactions of NaAlH(4). The catalytic enhancement by Al(3)Ti doping significantly increased with increasing ball-milling time. Moreover, it was noted that dehydriding kinetics and cycling performance of the Al(3)Ti-doped NaAlH(4) were highly dependent on the starting material, 1:1 NaH/Al mixture or NaAlH(4). The combined property and phase examinations suggest that Al(3)Ti may act as active species to catalyze the reversible de-/hydrogenation of NaAlH(4). (c) 2006 Published by Elsevier B.V.
