Abstract
An electrodynamic model of the redox sorption of oxygen from water on metal-ion-exchange nanocomposites’ (NCs) granular layers is proposed. It features a simultaneous description of the oxygen reduction process along the electrochemical and chemical routes. Due to the inhomogeneous oxidation of metal nanoparticles by oxygen, the granular layer of the NC ohmic resistance, which varies in height and time, is taken into account. The adequacy of the model was tested on a copper-containing NC.
