METHOD OF CYCLIC VOLTAMMETRY FOR ELECTROCHEMICAL STUDIES OF GRAPHITE MATERIALS IN ALKALINE MEDIUM

The data on the electrochemical and electro catalytic properties of natural (NG), oxi-dized (OG), oxidize expanded (TWG) graphite and graphite oxide (GO) are presented. The evaluation of the electrocatalytic activity of graphites for the reduction of dioxygen in an al-kaline solution was carried out. The effective number of electrons for the given process was determined.

ELECTROCHEMICAL PROPERTIES OF THERMALLY EXPANDED GRAPHITES AND OXIDIZED GRAPHITES MODIFIED WITH TRANSITION METAL SALTS

The data were presented on study by electrochemical properties (the redox potential, the effective number of electrons, half-wave potential, current density) of thermally expanded graphite and oxidized graphite modified with metal salts (Fe2+, Co2+, Ni2+, Cu2+, Zn2+) in al-kaline environment.
