英文摘要: LiBH(4) nanoparticles supported by disordered mesoporous carbon CMK-3, denoted as nano-LiBH(4)/C(mesoporous), were synthesized in the present work. Nano-LiBH(4) in this sample was destabilized significantly, resulting in more favorable latent heat of dehydrogenation (40 kJ/mol H(2)), large amount of dehydrogenation capacity (14wt%) below 600 degrees C and reversible capacity of 6.0wt% H(2) at 350 degrees 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-LiBH(4) and reverse hydrogenation. (c) 2007 International Association for Hydrogen Energy. Published by Elsevier Ltd.
