<p>Provided are oxidized carbon nanotube structures including aggregates, networks, assemblages, rigid porous structures, electrodes, and mats. Oxidized carbon nanotubes may be formed by conducting gas-phase oxidation on carbon nanotubes. Gas-phase oxidation may be conducted by contacting carbon nanotubes with gas-phase oxidizing agents, such as CO2, O2, steam, N2O, NO, NO2, O3, ClO2, and mixtures thereof. Near critical and supercritical water can also be used as oxidizing agents. Oxidized carbon nanotube structures may include a plurality of oxidized carbon nanotubes along with a supported catalyst, which was used to grow carbon nanotubes prior to oxidation. The supported catalyst may be subjected to gas-phase oxidation and may remain with the oxidized carbon nanotubes in oxidized carbon nanotube structures.</p> |
