- 化学化工－已发表论文 
采用化学气相沉积法 (CCVD) ,用乙炔为原料气 ,在 β Zeolite负载的镍基催化剂上成功地合成了外径 30～ 4 0nm ,内径 2～ 3nm ,长度达四十几微米管径均匀的多层碳纳米管 (MWNTs) .研究了MWNTs从分子筛中分离和纯化的方法 .MWNTs were synthesized on Ni/β zeolite catalyst by CCVD method. The results showed that the shape of carbon nanotubes is very regular. The outer diameter is about 30 nm and inner diameter is in the region of 2 to 3 nm. Moreover, the MWNTs can be conveniently separated and purified from β zeolite. The result has significance for large scale synthesis of MWNTs.
