Anode with the Active Layer for Electrosynthesizing Ozone in a System with Solid Polymer Electrolyte

详细

The synthesis of catalytic coatings on porous titanium electrodes by the method of magnetron sputtering is considered. The content of dopant ions Fe³⁺ and F^– is optimized as regards the activity and stability of the PbO₂ catalyst in the reaction of ozone electrogeneration as well as the current efficiency with respect to ozone. It is shown that the best characteristics of the electrochemical ozone generator are observed on the PbO₂ catalyst doped with Fe³⁺ and F^– ions in the amount of 3–4 and 1–2 at %, respectively.
