Investigation of reaction between LiNH2 and H2

Abstract The reactions for LiNH 2 under a H 2 and an Ar flow were investigated, respectively. The results showed that LiNH 2 can be converted into LiH and NH 3 by reacting with H 2 under a H 2 flow condition, whereas LiNH 2 is converted into Li 2 NH and NH 3 by decomposition under an Ar flow. Moreover, the reaction between LiNH 2 and H 2 can be accelerated by mixing LiNH 2 with LiH as well as doping LiNH 2 with TiCl 3 . The confirmation of reaction between LiNH 2 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.
