ABSTRACT:
Carbon nanostructures are formed from a carbon precursor and catalytic templating nanoparticles and are treated with a severe oxidative agent to introduce oxygen-containing functional groups to the surface of the graphitic material. Methods for manufacturing carbon nanostructures generally include (1) forming a precursor mixture that includes a carbon precursor and a plurality of catalytic templating particles, (2) carbonizing the precursor mixture to form an intermediate carbon material including carbon nanostructures, amorphous carbon, and catalytic metal, (3) purifying the intermediate carbon material by removing at least a portion of the amorphous carbon and optionally at least a portion of the catalytic metal, and (4) treating the intermediate carbon material with a severe oxidative treatment to increase surface functionalization. Examples of oxidative treatments include (i) a mixture of nitric acid and sulfuric acid, (ii) a solution of hydrogen peroxide, or (iii) a mixture of sulfuric acid and hydrogen peroxide.
