Advantages

Exceptional Corrosion Resistance: Similar to Ru-Ti and Ir-Sn-Ti anodes, the presence of titanium oxide ensures outstanding corrosion resistance, even in harsh environments and under high current densities.
Enhanced Electrocatalytic Activity: The combination of RuO2 and IrO2 provides a broader range of electrocatalytic activity than single-metal oxide anodes. This makes them effective for various reactions, including oxygen evolution, chlorine evolution, and the oxidation of different organic compounds.
Synergy and Selectivity: The interaction between RuO2 and IrO2 can lead to synergistic effects, enhancing the overall catalytic activity and selectivity for specific reactions compared to individual oxides.
Stability and Durability: Ru-Ir-Ti anodes demonstrate good stability over a wide potential range and are mechanically robust, ensuring long-term performance and durability.

Application Areas

Applications

Water electrolysis: For hydrogen production, the high activity of both oxides is used for the oxygen evolution reaction.
Chlor-alkali industry: Production of chlorine and caustic soda, where the combined properties of RuO2 and IrO2 ensure efficient chlorine evolution and long-term stability.
Wastewater treatment: Effective for oxidizing organic pollutants and disinfection processes.
Electrochemical synthesis: Utilized to produce various organic and inorganic compounds, benefiting from the tunable selectivity and activity.
Metal electrowinning and electrorefining: Extracting and purifying metals from solutions, leveraging the stability and activity of the mixed oxide coating.
Swimming Pool Disinfection: Utilized in salt chlorine generators for pool sanitation.
Food Processing: Employed in disinfection systems for fruits and vegetables.
