摘要

Carbon nanostructures (fullerenes and nanotubes) were obtained using the carbon arc technique employing homoegeneous carbon-iron and carbon-cobalt-nickel aodes. The influence of these catalysts on the arc plasma was studied by optical emission spectroscopy to determine temperatures and C_2 radical content in the arc zone. The solid products were analyzed by spectrophotometry and mass spectrometry to determine the C_60 yield and relative mass distributions of the higher fullerenes, resepctively. SEM and TEM techniqeus were used to affirm the presence of carbon nanotubes in the resulting soot product.
