1, Ruthenium coated titanium electrode

The electrodes have low chlorine evolution overpotential and high oxygen evolution overpotential, and are mainly used in various chlorine evolution applications, such as chlor-alkali industry, cathodic protection and the like. Such electrode coatings include an initial niobium titanium coating (Ru-Ti) and Ru-Ir, RuTi, etc. coatings developed on this basis.

2, Iridium coated titanium electrode

In some electrolysis processes, such as electrolytic extraction of non-ferrous metals, electroplating industry, electrochemical reduction of organic matter, etc., the design reaction of the anode is an oxygen evolution reaction, so it is desirable to develop an anode material with low oxygen evolution potential and lanthanide coating. The layer of titanium electrode was developed in this context. Such electrode coatings include coatings such as Ir-Ta, Ir-Sn, Ir-Ru-Pd-Ti. Among them, the Ir-Ta coated titanium electrode is the most successful oxygen evolution electrode.

3. Platinum anode: Titanium is the substrate. The surface is plated with precious metal platinum, and the thickness of the coating is generally 0.1-5 um.
