MMO titanium anode is an electrode coated with precious metal oxide on a titanium substrate, which has electrocatalytic activity and good conductivity. MMO titanium anodes are usually coated with precious metal oxides (such as ruthenium, iridium, etc.) on titanium substrates and fired at high temperatures. This structure enables MMO titanium anodes to exhibit excellent performance in electrochemical reactions and are widely used in various electrochemical processes.
Structure and Characteristics
The main structure of MMO titanium anode is to cover a layer of precious metal oxide film on the titanium substrate. Industrial pure titanium is usually chosen as the titanium substrate to ensure its corrosion resistance and mechanical strength. The precious metal oxide coating endows the electrode with electrocatalytic activity and conductivity, making it perform outstandingly in electrochemical reactions.
Application
MMO titanium anode is widely used in the following fields due to its excellent electrocatalytic activity and conductivity:
Nonferrous metal electrolysis production: used for extracting and recovering non-ferrous metals during the electrolysis process.
Chloride electrolysis: used in the process of chloride electrolysis for the generation of chlorine gas.
Seawater electrolysis: used in the process of electrolyzing seawater to produce chlorine gas and sodium hydroxide.
Metal foil manufacturing: used for the manufacturing and surface treatment of metal foil.
Industrial electroplating: providing high demand electroplating effects during the electroplating process.
Cathodic protection: a cathodic protection system used to prevent metal corrosion.
Electrodialysis: used in water treatment and ion exchange processes.
Industrial wastewater treatment: used to treat harmful substances in industrial wastewater.
Advantages and disadvantages
The advantages of MMO titanium anode include:
High electrocatalytic activity: capable of efficiently carrying out electrochemical reactions at lower voltages.
Good conductivity: ensuring effective transmission of current.
Corrosion resistance: The titanium substrate and precious metal oxide coating make it excellent in various electrolytes.
Long lifespan: Due to strong corrosion resistance, the service life is relatively long.
The disadvantages are relatively few, mainly including:
High cost: Precious metal oxide coatings increase manufacturing costs.
Limited environmental adaptability: Certain specific environments may require specially designed MMO anodes.
In summary, MMO titanium anodes have been widely used in various industrial fields due to their excellent electrocatalytic activity and conductivity, as well as good corrosion resistance and long lifespan.
