A process for doping carbon materials is disclosed which comprises combining a Ce (IV) salt dissolved in a solvent comprising water with a carbon material comprising CNT or graphene wherein the Ce (IV) salt is selected from a Ce (IV) ammonium salt of a nitrogen oxide acid, Ce (IV) ammonium salt of a sulfur oxide acid, Ce (IV) salt of a lower alkyl organo-sulfur acid, or Ce (IV) salt of a substituted lower alkane organo-sulfur acid. In one embodiment the Ce (IV) salt is selected from Ce (IV) ammonium nitrate, Ce (IV) ammonium sulfate, Ce (IV) lower alkylsulfonate, or Ce (IV) trihalo lower alkanesulfonate.
