Abstract

We report the production of carbon nanotubes of high purity by a vapor phase growth method using a catalytic reaction of a tungsten-containing organic compound (C14H10O7W) and acetylene mixture. The products were multi-walled carbon nanotubes with hollow cores. Transmission electron microscopy investigation revealed that the graphitic layers at the inner region were highly crystallized but the graphitic layers at the outer region had a wavy structure. We have demonstrated the effective production of carbon nanotubes using a tungsten-based catalyst.
