摘要：

The reactions for LiNH2 under a H-2 and an Ar flow were investigated, respectively. The results showed that LiNH2 can be converted into LiH and NH3 by reacting with H, under a H-2 flow condition, whereas LiNH2 is converted into Li2NH and NH3 by decomposition under an Ar flow. Moreover, the reaction between LiNH2 and H-2 can be accelerated by mixing LiNH2 with LiH as well as doping LiNH2 with TiCl3. The confirmation of reaction between LiNH2 and H-2 is helpful for the deeper insight in the systems of Li-N-H and Li-Mg-N-H for hydrogen storage materials. (C) 2007 Elsevier B.V.
