MMO (Mixed Metal Oxide) titanium anodes are electrode materials with titanium as the substrate and a surface coating of mixed metal oxides (such as iridium, ruthenium, and platinum). They are widely used in electro-catalytic oxidation wastewater treatment due to their excellent electro-catalytic activity and corrosion resistance.In the electro-catalytic oxidation wastewater treatment process, the MMO titanium anode acts as the anode. Under the action of a DC electric field, water molecules undergo electrochemical reactions on its surface, generating reactive oxygen species (ROS) such as hydroxyl radicals (·OH), ozone (O₃), and hypochlorite ions (ClO⁻).These reactive oxygen species have strong oxidizing properties, which can oxidize and decompose pollutants in wastewater—including organic compounds, cyanides, and heavy metal ions—into harmless substances.
Advantages
1. Strong Corrosion Resistance
The dense oxide film on the titanium substrate and the coated mixed metal oxide layer enable the MMO titanium anode to remain stable in harsh wastewater environments (e.g., strong acids, strong alkalis, and high salinity). It is not easily corroded, with a typical service life of 3–5 years—far longer than traditional anode materials like graphite or lead.
2.High Electro-Catalytic Efficiency
The MMO coating has excellent electro-catalytic activity, which significantly reduces the overpotential for oxygen evolution and chlorine evolution, thereby improving the efficiency of electrolytic reactions. For instance, the addition of RuO₂ lowers the oxygen evolution overpotential from 1.6V to 1.3V, reducing the operating voltage by 30% under the same current density and effectively cutting energy consumption.
3. Environmental Friendliness
No chemical agents are added during the electrolysis process, avoiding secondary pollution that may occur with traditional chemical treatment methods. Moreover, the reactive oxygen species generated by electro-catalytic oxidation can effectively degrade pollutants in wastewater, reducing pollutant emissions and meeting environmental discharge standards.
4.High Current Density Tolerance
Compared with traditional anode materials (e.g., graphite, lead), MMO titanium anodes can withstand higher current densities (up to 2000 A/m²). Within the same electrolytic cell volume and treatment time, they can process more wastewater, significantly improving treatment efficiency.
Application Scenarios
1.Cyanide-Containing Wastewater Treatment
Common in industries such as electroplating and mining, cyanide-containing wastewater is highly toxic. The MMO titanium anode uses electrolytic oxidation to decompose cyanides into harmless substances (N₂ and CO₂), achieving the harmless treatment of cyanide-containing wastewater.
2.Phenol-Containing Wastewater Treatment
Phenol-containing wastewater (from petrochemical, coking, and pharmaceutical industries) is difficult to biodegrade. Through electro-catalytic oxidation, the MMO titanium anode effectively degrades phenolic compounds, reducing the phenol content in wastewater to meet discharge standards.
3.High-Salinity Wastewater Treatment
High-salinity wastewater (e.g., from chemical engineering, mariculture) often contains high concentrations of Cl⁻. The MMO titanium anode can generate chlorine gas (Cl₂) and sodium hydroxide (NaOH) through electrolysis, realizing integrated desalination and disinfection of wastewater. At the same time, it can oxidize and remove organic compounds and other pollutants in the water.
4.Refractory Organic Wastewater Treatment
For wastewater containing refractory organics (e.g., dyes, pharmaceuticals, and pesticides), the MMO titanium anode breaks the stable chemical bonds of organic molecules via strong oxidizing reactive oxygen species, improving the biodegradability of wastewater (increasing B/C ratio from <0.2 to >0.3) and creating conditions for subsequent biological treatment.

Production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
