Abstract
Fabrication, design and investigation of functional properties of composite materials based on titanium suboxides with low noble metal content for use in electrocatalysis has been investigated. The study particularly focuses on electrode coatings derived from titanium dioxide modified with platinum and palladium. The structural, electrocatalytic, and corrosion-resistant properties of these materials were systematically investigated. It was demonstrated that thermal treatment significantly enhances the catalytic efficiency of the coatings by reducing the oxygen evolution overpotential and improving the efficiency of hypochlorite synthesis. Optimal thermal treatment conditions (500 °C, 3 hours) were identified, resulting in increased stability of the anodes containing Pt and Pd layers, as evidenced by a service life of 176 hours. The study highlights the potential of these composites for applications in oxygen evolution reactions and hypochlorite synthesis, owing to their high stability, selectivity, and cost-effectiveness
