Classification of Titanium Anodes

Mixed Metal Oxides (MMO) refer to compounds formed by the combination of two or more metal elements with oxygen. They possess unique physical, chemical properties and structural characteristics, and are widely used in various fields.

Ruthenium Iridium Coating is a metal oxide coating with ruthenium (Ru) and iridium (Ir) as the main active components, which is often loaded on metal substrates such as titanium (Ti). Titanium as the substrate provides good mechanical strength and toughness for the anode. Ruthenium and iridium oxides are the active components of the anode. Ruthenium can enhance the electrocatalytic activity of the material, and iridium can enhance the stability and corrosion resistance of the material. By adjusting the ratio of ruthenium and iridium, the electrochemical properties of the material can be precisely adjusted to adapt to different application scenarios.
In a strongly acidic and high chloride ion concentration electrolysis environment (such as the electrolysis of saturated brine), the coating is not easily corroded and its service life can reach more than 3 years.
With the balance of “catalytic activity – corrosion resistance – stability”, the ruthenium-iridium coating has become an irreplaceable functional material in the electrochemical field. With the development of the new energy and environmental protection industries, its application scenarios are still expanding.

During the electrolysis process, the iridium tantalum titanium anodes, as the provider of electrons, participates in the electrochemical reaction. Taking the electrodeposition extraction of non-ferrous metals as an example, the metal ions to be extracted in the electrolyte that has undergone leaching and purification are reduced at the cathode to obtain pure metal. Meanwhile, the iridium-tantalum-titanium anode undergoes an oxidation reaction at the anode. Precious metals such as iridium and tantalum in its coating play an electrocatalytic role, reducing the overpotential and cell voltage of the anodic reaction, enabling the reaction to proceed efficiently with low energy consumption.

Platinum-titanium anodes use Gr1/Gr2 grade pure titanium (purity ≥99.6%) as the base material, with a 0.5-5μm platinum layer formed on the surface through electroplating or thermal decomposition coating processes. The titanium substrate provides mechanical support and an anti-corrosion base, while the platinum layer endows the electrode with excellent conductivity (resistivity as low as 2×10⁻⁶Ω・cm) and catalytic activity. For example, in hydrogen production by water electrolysis, the platinum layer can reduce the overpotential of the oxygen evolution reaction (OER) to 1.385V, saving 10%-15% more energy compared to traditional ruthenium-iridium coatings.

Lead dioxide is deposited on the surface of titanium mesh by electroplating to form a double-plated three-dimensional structure (α-PbO₂ bottom layer + β-PbO₂ top layer). The coating has strong adhesion to the substrate, a high oxygen evolution potential of ≥1.70V (vs. SCE), and strong oxidizing ability, which can efficiently degrade organic substances. Lead dioxide-titanium anodes occupy an important position in fields such as industrial wastewater treatment, hydrometallurgy, and electroplating due to their excellent electrochemical performance, high stability, and cost advantages.
