英文摘要: In this paper, two LiAlH4-NaNH2 samples with LiAlH4 to NaNH2 molar ratio of 1/2 and 2/1 were investigated, respectively. It was observed that both samples evolved 2 equiv H-2 in the ball milling process, however, the reaction pathways were different. For the LiAlH4-NaNH2 (1/2) sample, Li3Na(NH2)(4) and NaAlH4 were formed through cation exchange between reactants. The NaAlH4 formed further reacts with Li3Na(NH2)(4) and NaNH2 to give H-2, NaH and LiAlN2H2. For the LiAlH4-NaNH2 (2/1) sample, Li3Na(NH2)(4), LiNH2 and NaAlH4 were formed firstly through the same cation exchange process. The resulting LiNH2 reacts with the remaining LiAlH4 and produces H-2 and Li2AlNH2. (C) 2010 Elsevier Inc. All rights reserved.
