Abstract

The work is devoted to the development of technology for obtaining and studying the physicochemical characteristics of oxide coatings of noble (IrO2, RuO2), rare earth (Ta, Nb, Ce) metals, and TiO2, SnO2 based on a titanium, that has undergone the primary chemistry.Important technological characteristics (adhesion, roughness) which show the principal possibility of using the obtained samples as anode materials for the electrolysis of aqueous solutions for the purpose of purifying wastewater or the production of sodium hypochlorite as a reagent were determined. Studies conducted by the XPS, obtained microphotographs and surface profiles confirm the prospect of using these oxide coatings as electrode materials.The electrochemical characteristics we studied make it possible to determine the field of application of the obtained electrodes more accurately for the reaction of chlorine and oxygen evolution with RuO2 and IrO2.

Keywords: Ruthenium oxide, cerium oxide, iridium oxide, tin oxide, titanium oxide
