Abstract
A process 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 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 alkyllsulfonate, or Ce (IV) trifluoro lower alkanesulfonate. A product is produced by this process. An article of manufacture comprises this product on a substrate.
