Djelali V. Interphase impedance. Faraday and adsorption processes.

Object of research: electrode processes of discharge - ionization of ions and adsorption Red-Ox of the forms on metal electrodes of high cleanness. A subject of research: the gear, kinetics and power engineering delayed faradau and adsorption processes and their interphase impedance. Research techniques: an impedance spectroscopy, impedance spectroscopy with the extended frequency band, capacitance-resistance. The non-linear equations of electrochemical kinetics for the rate-determining process discharge-ionization with the account of the resistance to charge transfer were deduced for the first time. The Broensted relation for the electrochemical reactions, which includes the resistance to charge transfer was obtained. It was shown, that standard overstrain is the remaining value at realization of the delayed discharge-ionization mechanism while changing the electrode potential. The new formulation for the electrode processes activation energy was proposed. It allows calculating this activation energyfrom the real contributions in the impedance spectra. The theory, which describes the dependence of the adsorption Frumkin - Melik-Haykazyan impedance from the polarization potential in cases of different types of adsorption isotherms, was developed. The existence of the linear dependencies of the types lnRA = f(E) and lnCA = f(E) was confirmed both theoretically and experimentally for the ionic and atomic forms of the adsorbed particles. Field of application: applied, an experimental and theoretical electrochemistry, physics and chemistry of interphase boundaries.
