采用化学气相沉积法，利用含有铁原子和钼原子的相同分子纳米团簇作为催化剂，制备出了均匀和小直径的单壁碳纳米管（SWNTs）。实验得到的单壁碳纳米管的平均直径为1.0 nm，直径分布的标准差为17%。利用原子力显微镜和拉曼光谱测定了纳米碳管的直径。
Uniform and small-diameter single-walled carbon nanotubes (SWNTs) have been produced using identical molecular nanoclusters containing Fe and Mo atoms with a defined molecular formula and a specific structure as catalysts in a chemical vapor deposition method. The average diameter of the SWNTs produced in these experiments is 1.0 nm with a standard deviation for the diameter distribution of 17%. The diameters of SWNTs were obtained by atomic force microscopy and Raman spectroscopy.
