MMO (Mixed Metal Oxide) titanium anodes are widely used in water electrolysis,The mixed metal oxide coating (e.g., iridium oxide (IrO₂), ruthenium oxide (RuO₂), or tantalum oxide (Ta₂O₅)) catalyzes the OER, reducing the reaction’s overpotential (the extra voltage needed to drive the reaction) and improving energy efficiency. The titanium substrate provides mechanical strength and corrosion resistance in the harsh, oxygen-rich electrolytic environment.
Advantages for Water Electrolysis
High Electrocatalytic Activity: MMO coatings (especially IrO₂-based ones) lower the overpotential for OER, reducing the energy required to split water. For example, compared to traditional platinum anodes, MMO titanium anodes can achieve similar OER rates at 10-20% lower cell voltage.
Corrosion Resistance: The titanium substrate is inert in acidic, alkaline, or neutral electrolytes, while the MMO coating resists oxidation and degradation even under high current densities (up to 1000 A/m² or more). This ensures a long service life (typically 5,000-10,000 hours in continuous operation).
Stability: Unlike graphite anodes (which erode and contaminate the electrolyte) or lead-based anodes (which are toxic and unstable), MMO titanium anodes maintain their dimensions and performance over time, ensuring consistent H₂/O₂ production.
Application Scenarios
Green Hydrogen Production: MMO titanium anodes are critical in electrolyzers powered by renewable energy (solar, wind) to produce “green hydrogen,” a clean fuel with zero carbon emissions.
Industrial Electrolysis: Used in large-scale H₂ production for industries like ammonia synthesis, metallurgy, and fuel cells. For example, in alkaline electrolyzers for industrial H₂, MMO anodes reduce energy consumption by 10-15% compared to older nickel anodes.
Seawater Electrolysis: Modified MMO coatings (resistant to chloride oxidation) enable direct electrolysis of seawater, avoiding the need for desalination and reducing costs in coastal regions.
Small-Scale Systems: Integrated into portable or distributed electrolyzers for on-site H₂ generation (e.g., fueling stations, remote power systems).

Production
Brush coating.
Specific operation as follows:
Firstly,making the coating solution according to the type and the area of the platinum electrode; secondly ,put the solution on the surface evenly, then put them into the drying furance for drying; thirdly,we need to oxidate in the high temperature oxidation furance;Lastly, dry it to room temperature. Then,repeat these steps until you run out the configuration solution.
