| 摘 要： | 研究了以乙炔为基本原料，用Ｎ２做载流气体；以纳米钻颗粒为催化剂在７００～８００℃常压下纳米碳管的宏观量制备．粗产品中纳米碳管的含量接近５０％，而且纳米碳管缺陷很少，直而长，石墨化好．纳米碳管的形核过程是因为碳在催化剂表面分布不均匀造成的．纳米碳管的生长极限在１５ｍｉｎ左右，然后生长变得缓慢，纳米碳管的一般长度在５～３０μｍ．

| Abstract: | Acetylene cracked under normal pressure at 700-800℃ with active nanoscale cobalt particles as catalyst and carbon nanotubes were prepared on a large scale. The final product rate was above 50wt% after 10min growth, and also defects were almost nonexistent. The lengthes of the carbon nanotubes ranged from 5 to 30μm. Non-well distributed carbon on catalyst surface accelerated the nucleating process. The growing time limitation was about 15min and then growing process became slow. |
