Temperature Dependence of the Kinetics of Ozone Reduction on the Platinum Surface

Abstract

We study the redox processes in ozonized sulfuric acid solutions at different temperatures. It is shown that the changes in the effective activation energy within a potential range of 0.75 V are connected with the transition from the ozone reduction via the active forms of oxygen, e.g., hydroxide ions or hydrogen peroxide, to its direct reduction on the metal. It is also discovered that the ozone reduction through hydrogen peroxide is improbable at low temperatures.
