Electrochemical characteristics for the 1 M (C2H5)(3)CH3NBF4 + acetonitrile (AN)carbide-derived carbon nanoporous (prepared from TiC, alpha-SiC, Mo2C, Al4C3 and B4C) interface have been established by cyclic voltammetry and electrochemical impedance spectroscopy. The gas adsorption measurements have been used for the obtaining the specific surface area, pore size distribution, nanopore volume and other characteristics, dependent on the precursor carbide used (nanopores are pores in the range of 2 nm and below-i.e. micropores according to IUPAC classification). The region of ideal polarizability, values of series and parallel capacitances, parallel resistance and capacitance and other characteristics dependent on the precursor carbide have been established.
