Investigation of reaction between LiNH2 and H2

The reactions for LiNH2 under a H2 and an Ar flow were investigated, respectively. The results showed that LiNH2 can be converted into LiH and NH3 by reacting with H2 under a H2 flow condition, whereas LiNH2 is converted into Li2NH and NH3 by decomposition under an Ar flow. Moreover, the reaction between LiNH2 and H2 can be accelerated by mixing LiNH2 with LiH as well as doping LiNH2 with TiCl3. The confirmation of reaction between LiNH2 and H2 is helpful for the deeper insight in the systems of Li–N–H and Li–Mg–N–H for hydrogen storage materials.
