Abstract (en)
[origin: WO2004052781A1] A method of purifying an impure sample of carbon nanotubes is described comprising a method of purifying an impure sample of carbon nanotubes comprising annealing them in air or another oxygen-containing gas which, apart form oxygen, is inert to carbon nanotubes under the conditions used and then heating them in a medium which oxidises graphene only at a temperature of at least 330°C at atmospheric pressure or a medium equivalent thereto using a form of non-contact electromagnetic heating.
