摘要：

Ti-doped NaAlH4 can be prepared in a simple way by hydrogenation of aluminum powder in conjunction with sodium hydride in the presence of Ti(OBun)(4) (Bu-n = n-C4Hg) as a dopant. After a few hydrogenation/dehydrogenation cycles the material reaches a storage capacity of similar to 4 wt% H-2 and exhibits reaction rates comparable to or exceeding those previously found for NaAlH4 doped with Ti(OBun)(4) in organic solvents.
