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.
