Abstract

In this report, we will first describe the phase determination before and after the hydrogenation of Li3N, and then clarify the fundamental hydrogen storage (desorption) properties with/without the partial cation substitutions in LiNH2. Combined analyses both the in situ Raman and thermal desorption spectroscopies indicate that the hydrogen desorption reaction from LiNH2 starts around 550 K, and that from Li2NH around 700 K, respectively, in heating process under 0.1 MPa argon. The starting and ending temperatures for the hydrogen desoprtion reaction lowers about 50 K by the partial cation substitution of Li by Mg.
