摘要
主要阐述了用流动催化剂法制备的纳米炭纤维的储氢特性，发现在室温下纳米炭纤维可以快速大量吸氢纳米炭纤维的储氢量远远高于目前各种储氢材料的储氢容量100nm左右的炭纤维的储氢容量高达10％以上（质量分数），如此高的储氢容量使其在燃料电池等方面具有厂阔的应用前景.
A new high-capacity reversible hydrogen storage material, vapor-grown carbon nanofibers (VGCNFs). has been synthesized by catalytic decomposition of benzene. The VGCNFs are found to absorb and desorb quickly and easily large quantities of hydrogen under certain pressures at room temperature. The hydrogen uptake capacity of VGCNFs over 10% (mass fraction) was obtained when the VGCNFS were exposed to hydrogen in 8-12MPa at room temperature, which is much higher than that of any other hydrogen storage system. The very high hydrogen storage in VGCNFs suggests that they may be promising for the applications of hydrogen fuel cell electric vehicles and other fuel cells.
