Single-walled carbon nanotubes etched in aqua regia (SWCNT<sub>et</sub>) and doped with nitrogen (N-SWCNT) were studied by XPS, electron microscopy and IR spectroscopy. Various oxygen-containing functional groups were found to reside on the surface of initial SWCNT<sub>et</sub>. Upon treatment of SWCNTet in 40%NH3-1%С<sub>2</sub>Н<sub>2</sub>-C<sub>2</sub>H<sub>4</sub>, polymerization and condensation of hydrocarbons resulted in the formation of a thin nitrogen-containing carbon coating. Specific capacitance per a weight of initial and nitrogen-doped carbon nanotubes in an aqueous electrolyte with 1 M H<sub>2</sub>SO<sub>4</sub> was measured. Specific capacitance of carbon electrodes was found to change symbately with the content of nitrogen-containing functional groups on the SWCNT surface.</span></p>}, number={4}, journal={Eurasian Chemico-Technological Journal}, author={Chesnokov, V.
