PLASMA SYNTHESIS OF NANOCARBONS

摘要

Nanocarbons (fullerenes, nanotubes, "carbon onions", encapsulates,...) are efficiently produced by using a sublimation of carbon-bearing materials followed by the condensation of a carbon gas. Due to the very high sublimation temperature of carbon (close to 4000 K) different thermal plasma techniques (e.g., arc and radio frequency discharges, laser excitation) have been successfully demonstrated for synthesis of gram quantities of these nanomaterials. Non-thermal plasmas have also been reviewed as a source of aligned elongated nanocarbons.
