absorption fine structure (EXAFS) and Raman spectroscopies. We discuss here the charge
transfer and the iodine–carbon interaction as a function of the carbon nanostructures
(graphite, multi-walled, double-walled and single walled nanotubes). The results show that
iodine is weakly adsorbed on the surface of all multi-walled nanotubes. By contrast, a
charge transfer between iodine and single walled nanotubes is evidenced.
