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.
