Paper Title:
Growth of Single-Walled Carbon Nanotubes by Disproportionation of CO Over Co-Re/SiO2 Catalysts
  Abstract

A series of silica supported Co-Re catalysts was prepared and used as catalysts for the synthesis of single-walled carbon nanotubes (SWNT) by carbon monoxide disproportionation at 750 – 950 °C. The characterization of catalysts suggests that good quality of SWNT was obtained from partially reduced and completely reduced cobalt-rhenium oxide. The carbon products were characterized by Raman spectroscopy, temperature programmed oxidation (TPO) and transmission electron microscope (TEM). The effects of reaction parameters such as molar ratio of Co to Re, reduction temperature, and reaction temperature were investigated. It was found the the synergism of Co and Re in the catalytic production of SWNT leads to high selectivity of SWNT.
