The structural reorganization of carbon nanoparticles into single-wall nanotubes via high temperature annealing in absence of metal catalysts, was monitored by photoemission and x-ray absorption spectroscopy. It has been found that for this system an advanced graphitization process is made possible by the peculiar nanoparticle internal structure containing extended sp(2) coordinated domains with a sizable degree of ordering. Possible mechanisms for the formation of nanotubes via self-assembling of carbon aggregates are discussed.

Abstract
The structural reorganization of carbon nanoparticles into single-wall nanotubes via high temperature annealing in absence of metal catalysts, was monitored by photoemission and x-ray absorption spectroscopy. It has been found that for this system an advanced graphitization process is made possible by the peculiar nanoparticle internal structure containing extended sp(2) coordinated domains with a sizable degree of ordering. Possible mechanisms for the formation of nanotubes via self-assembling of carbon aggregates are discussed.File in questo prodotto:
