Abstract
High-surface area carbon nanotubes having targeted, or selective, species of oxygen containing species levels, types and/or content on either or both of the interior and exterior of the tube walls are claimed. Such carbon nanotubes can have little to none inner tube surface oxygen containing species, or differing amounts and/or types of oxygen containing species between the tubes' inner and outer surfaces or amongst the carbon nanotubes. Additionally, such high-surface area carbon nanotubes or their assemblages may have greater lengths and diameters, creating useful mechanical, electrical, and thermal properties.
