Abstract

It was found that the hydrogenation kinetics for the LiNH₂ system can be drastically improved by introducing a small amount of KNH₂ or KH (5 mol%). The reason for the improvement is that KNH₂ or KH can interact with LiNH₂ forming a KLi₃(NH₂)₄ ternary amide phase with superior reactivity to hydrogen (H₂).
