Iridium Oxide Electrode for Oxygen Evolution
Xuboti offers a ruthenium/iridium coated DSA titanium anode for oxygen precipitation. The MMO coating of the titanium anode is optimized for maximum oxygen production. It provides excellent coating strength and adhesion to the substrate for extended service life. We supply tens of thousands of titanium anodes to the domestic market and to markets in more than 20 countries worldwide.
Product Introduction
Basic Information:
In electrolytic processes, such as electrolytic extraction of non-ferrous metals, electroplating industry, electrochemical reduction of organic materials, etc., the anode is designed to react with oxygen precipitation, and the electrolyte is particularly oxidizing, such as sulfuric acid, nitric acid, hydrogen peroxide and other environments. Therefore, we hope to develop a corrosion-resistant anode material with low oxygen precipitation overpotential, and it is in this context that iridium oxide electrode for oxygen evolution are developed. These electrode coatings include Ir-Ta, Ir-Ta-Co, Ir-Ta-Sn and other coatings. Among them, iridium-tantalum coated titanium electrode is the most successful oxygen precipitation electrode. Tantalum is a precious metal and a stabilizer, and after adding the same molar z mass of tantalum in the titanium coating, it can greatly improve the service life of the anode in the strong oxidizing solution.
