Different carbon allotropes, including vulcan carbon, multiwall carbon nanotubes, graphene, and nanodiamonds, were processed by chemical purification and treated in a mixture of H2SO4-HNO3. The materials were characterized by infrared and Raman spectroscopy as well as by scanning and transmission electron microscopy. Oxidative differences are indicated by Raman through the G band (similar to 1570 cm(-1)), D band (similar to 1340 cm(-1)), and G' band (similar to 2684 cm(-1)). The crystal size (L-a) and purity, relative to the amorphous carbonaceous material, were studied as well, along with the morphological changes induced by the treatments.
