MMO Titanium Electrode Technology and Industry Knowledge

Technical Principles of MMO Titanium Electrodes

MMO titanium electrodes are mixed metal oxide catalytic coatings. They are formed by thermal decomposition on the surface of a titanium substrate. During electrolysis, the coating acts as an active catalytic layer, promoting electrochemical reactions and protecting the titanium substrate from passivation.

Compared to traditional graphite electrodes, MMO titanium electrodes maintain dimensional stability during long-term operation. They are known as dimensionally stable anodes.

Oxygen evolution reaction (OER) and chlorine evolution reaction (CYR) are two major electrochemical processes in industrial applications. Different MMO coating formulations are selected based on the reaction. Ruthenium-based coatings are commonly used for chlorine evolution electrolysis, while iridium-based coatings are suitable for oxygen evolution electrolysis.

Operating Environment of MMO Titanium Electrodes

MMO titanium electrodes are suitable for the following harsh industrial operating environments:

High chloride ion concentration

Acidic solutions

Alkaline electrolytes

Seawater systems

High current density electrolysis systems

Titanium has strong corrosion resistance, and MMO titanium electrodes perform excellently in long-term continuous electrolysis applications.

Application industries include:

Industrial wastewater treatment

Electrochemical oxidation

Electrolytic copper foil production

Chlor-alkali industry

Hydrogen electrolysis

Electro-sterilization systems

Different coating systems should be selected based on temperature, pH value, and electrolyte composition.
