英文摘要: By adding a small amount of HMPA approximately 2.5 equivalent or ca. 8.1 wt% H-2 can be released from the LiAlH4-LiNH2 mixture at ambient temperature, which is similar to 370 degrees C lower than the corresponding solid-state dehydrogenation. NMR characterizations reveal the formation of intermediates, such as [AlH] and [AlN] species, during the dehydrogenation. LiNH2 induces the enrichment of [AlH] species in the liquid phase which further reacts with LiNH2 to produce H-2, Li2NH and Al.
