AbstractA composite of 2LiBH + nano-MgH∗ (Ti-catalyzed) shows significantly enhanced desorption kinetics compared to a conventional mixture of 2LiBH + MgH. The desorption mechanism was studied in the temperature range between 304 and 383 °C and under different pressure conditions. Desorption temperatures are 50-70 °C lower compared to conventional 2LiBH + MgH mixtures. During the hydrogen release from a mixture of 2LiBH + nano-MgH∗ at a hydrogen back-pressure of 0.4 MPa, MgB is formed and three different plateaus of equilibrium were detected. The reaction pathway is changed at 360 °C for the 2LiBH + MgH system when the nano-MgH∗ is used.
