Oxygen reduction behavior of RuO2/Ti, IrO2/Ti and IrM (M: Ru, Mo, W, V) Ox/Ti binary oxide electrodes in a sulfuric acid solution

“…Since iridium oxide is a typical material that resists corrosion in acidic solutions and is one of the outstanding electrocatalysts for oxygen evolution, IrO 2 -Ta 2 O 5 /Ti electrodes [8,9] have been used as oxygen-evolving anodes in the industrial electro-plating process, and the IrO 2 -RuO 2 -TiO 2 /Ti ternary oxide electrode is widely used as the Dimensionally Stable Anode (DSA ® ) catalyst-electrode in the electrolysis process for chlorine production in chlor-alkali industries [10]. Althogh basic investigations on the ORRs of iridium metal and compounds in acidic solutions have been published [11][12][13][14], reports on crystalline iridium oxide in acidic solutions have been scarce to date [15].…”

Potentiostatic Testing of Oxygen Reduction on Polymer Carbon Electrodes

“…where α is the cathodic transfer coefficient. In oxygen reduction, the observed rest potentials [10,32,33] are over 100 mV cathodic to the true equilibrium potential, E 0 r . For this reason, the applied overpotential is large enough so that the anodic current density can be neglected in relation to the cathodic current density, as represented by (3).…”
