摘要	LiBH(4) was incorporated into an activated carbon (AC) scaffold using a chemical impregnation method. Confinement of LiBH(4) Within the carbon nanopores was found to significantly improve both the hydrogen sorption kinetics and thermodynamics, compared to the bulk hydride. The LiBH(4)/AC sample starts to release hydrogen from just 220 degrees C, which is 150 degrees C lower than the onset dehydrogenation temperature of bulk LiBH(4). The dehydrogenation rate of the LiBH(4)/AC sample was one order of magnitude faster than that of bulk The temperature and hydrogen pressure conditions required for restoring the hydride were also significantly reduced when LiBH(4) was incorporated into AC. Preliminary study showed that the dissociation hydrogen pressure of LiBH(4) Could be enhanced by around one order of magnitude upon incorporating the hydride into AC. X-ray diffraction, Fourier transform infrared spectroscopy and nitrogen adsorption analyses were used to confirm the nanostructure of LiBH(4) in the AC scaffold. (C) 2008 Acta Materialia Inc.
