| Abstract: | The effect of phosphorus on the purity and morphology of carbon nanotubes by chemical vapor deposition method was investigated. It was found that the addition of phosphorus enhanced the catalysis of Fe and promoted the purity of carbon nanotubes. It was also found that the addition of phosphorus had a great effect on the morphology of carbon nanotubes. Chain-shaped carbon nanotubes, Fe nanowires-filled carbon nanotubes and bamboo-shaped carbon nanotubes were obtained and the graphitization of carbon nanotubes was enhanced. |
