Enhancement of the initial hydrogenation of Mg by ball milling with alkali metal amides MNH2 (M = Li or Na).
The introduction of 4 wt% of MNH2 (M = Li, Na) and other additives (Li, MgH2, NaCl, and NaBr) into pure Mg by ball milling greatly enhances the first hydrogenation (activation). Under 2 MPa of H2 at 608 K, the best activation performance is achieved with the NaNH2 additive.
