| 摘 要： | 为了提高CVD法（低温催化裂解烷烃类气体法）制备碳纳米管的产率，研究了镍/硅藻土催化剂的镍含量对制备碳纳米管的影响。采用透射电子显微镜（TEM）对还原后的催化剂和产物碳纳米管进行了分析。结果表明，催化剂中镍含量在一定范围内（6.4%-25.9%)，随着镍含量增加，催化剂活性提高，碳纳米管产率提高。但随镍含量的继续增加，催化剂的活性开始下降，碳纳米管的产率也相应下降。

| Abstract: | The influence of nickel content in catalyst on the preparation of carbon nanotubes (CNT) by CVD is studied systematically with an aim of improving the productivity. The carbon nanotubes and the catalysts are observed directly by transmission electron microscope(TEM). The experimental results show that the nickel content in catalyst is an important factor in the growth rate of carbon nanotubes. When the nickel content in catalyst is in the range of 6.4% to 25.9%, the catalytic activity of the catalyst and the relevant CNT yield pass through a maximum as the nickel content in catalyst increases. |
