LiBH4 nanoparticles supported by disordered mesoporous carbon CMK-3, denoted as nano-LiBH4 / Cmesoporous, were synthesized in the present work. Nano-LiBH4 in this sample was destabilized significantly, resulting in more favorable latent heat of dehydrogenation (40 kJ / molH2), large amount of dehydrogenation capacity (14 wt%) below 600 {ring operator} C and reversible capacity of 6.0 wt% H2 at 350 {ring operator} C. It was revealed that such destabilization results from two kinds of mechanisms: nano-dispersion and reaction with mesoporous carbon. Both mechanisms exert synergistic effects on the dehydrogenation of nano-LiBH4 and reverse hydrogenation. © 2007 International Association for Hydrogen Energy.
