الوصف: | Oxidation of conical and cylindrical carbon nanotubes (CNTs) was studied by physicochemical methods including high-resolution transmission electron microscopy. Differences in mechanisms of oxidation of these CNTs were revealed. The oxidation of conical CNTs with nitric acid first results in the formation of oxygen-containing groups uniformly distributed over the CNT surface, and then the carbon material undergoes fragmentation and destruction. The treatment of cylindrical CNTs with nitric acid results in oxidation at defect sites followed by a decrease in the tube thickness and a change in the pore structure of the carbon material. |
