摘　　要：采用CVD法制备了碳纳米管,并用TEM、BET吸附和129Xe NMR对碳纳米管的表面和内部结构进行了表征。通过BET吸附和129Xe NMR的结果对比分析,可以推断碳纳米管并非全部是中空的,而是被许多隔膜分隔成多个锥帽形空腔,这些隔膜一般为无定形碳,五元环或七元环。经过纯化后的碳纳米管具有优异的吸附性能,有望作为新一代的储氢材料。Carbon nanotubes （CNTs） were prepared by CVD method and characterized by TEM, BET adsorption and NMR methods. From comparison results of BET and NMR, it can be deduced that CNTs were not inner hollow in their full length, but cone-capped cavums, separated by some septa, such as amorphous carbon, heptagon or pentagon rings. After purification, CNTs have super adsorptive properties and are promising hydrogen storage materials.
