“…The dependence of the capacitance of the carbon phase on the electrode rational potential (E − E σ=0 , where E σ=0 is the zero charge potential), obtained assuming, to a first approximation, that this simplified model developed in [4,5] is valid for C(0001) with the cut surface (prepared according to the method described in [8,9]) as well as for polished edge plane of HOPG and glassy carbon electrodes, is given in figure 1. It should be noted that the Amokrane and Badiali model has been worked out for the homogeneous planar and smooth surfaces with translational invariance parallel to the metal surface [4,5]. Therefore, the values of C m obtained for the cut C(0001) | 0.1 M NaF+H 2 O as well as for C(0001) | 0.2 M (C 3 H 7 )NBF 4 +acetonitrile interface are realistic as the surface roughness of cut HOPC, i.e.…”

“…The model worked out by Amokrane and Badiali [4,5] gives good explanations of the capacitance data established for different metal electrodes in various aqueous and non-aqueous solutions [6,7]. In this theory, the metal is described using the density functional formalism, and the metal-solvent interaction as a sum of an attractive term (due to the dispersion forces (Van der Waals)) and a repulsion term (simulating the exclusion of the metal electrons from the electron cloud of the solvent molecules).…”

“…where N s is the number of dipoles per unit area; µ is the value of dipole moment; x = µE/kT (k is the Boltzmann constant) [4,5]. The effective field acting on a dipole was taken as E = 4πσ * /ε, where ε is an adjustable parameter having the meaning of an effective dielectric constant; and σ * is an effective charge density.…”

Electrical double layer and electrochemical characteristics at the nanoporous carbon | (C 2 H 5 ) 4 NBF 4 + acetonitrile interface have been studied by the cyclic voltammetry and impedance spectroscopy methods. The value of zero charge potential (0.23 V vs. SCE in H 2 O), the region of ideal polarizability and other characteristics have been established. Analysis of complex plane plots shows that the nanoporous carbon | x M (C 2 H 5 ) 4 NBF 4 + acetonitrile interface can be simulated by the equivalent circuit, in which the two parallel conduction parts in the solid and liquid phases are interconnected by the double layer capacitance in parallel with the complex admittance of hindered reaction of the charge transfer process. The values of the characteristic frequency depend on the electrolyte concentration and on the electrode potential, i.e. on the nature of ions adsorbed at the surface of nanoporous carbon electrode.
