CVD SYNTHESIS OF CARBON NANOTUBES

摘要

A method of production of carbon nanoparticles comprises the steps of: providing on substrate particles a transition metal compound which is decomposable to yield the transition metal under conditions permitting carbon nanoparticle formation; contacting a gaseous carbon source with the substrate particles; before, during or after said contacting step, decomposing the transition metal compound to yield the transition metal on the substrate particles; forming carbon nanoparticles by decomposition of the carbon source catalysed by the transition metal; and collecting the carbon nanoparticles formed.
