Abstract

Carbon nanotubes (CNT) were prepared using different carrier gases, with ferrocene as the catalyst precursor and acetylene as the carbon source. The effects of NH3 and nitrogen as carrier gases on the structure and morphology of CNT were investigated. CNT formed bamboo-like structure when grown in NH3. The growth of certain CNT could be explained by the base growth model, including tubular structured CNT grown in N2. The diameter of the CNT synthesized in NH3 was larger than that in N2. The alignment of the CNT grown in NH3 was better than that in N2.
