“…Various amide-hydride composites have been developed for hydrogen storage in recent years. Systems such as LiNH 2 -LiH, 1 LiNH 2 -LiBH 4 , [2][3][4] LiNH 2 -LiAlH 4 , 5 LiNH 2 -Li 3 AlH 6 , [6][7][8] LiNH 2 -CaH 2 , 9,10 LiAl(NH 2 ) 4 -LiH, 11 Ca(NH 2 ) 2 -2LiH, 12 Mg(NH 2 ) 2 -LiAlH 4 , 13 Mg(NH 2 ) 2 -Li 3 AlH 6 , 14 and Mg(NH 2 ) 2 -LiH [15][16][17][18][19] were extensively studied. Among these systems, the Mg(NH 2 ) 2 -LiH (1 : 2 in molar ratio) composite has been regarded as a promising candidate for onboard application due to its favorable reaction thermodynamics and relatively high capacity (5.6 wt% H 2 ).…”
