Ruthenium-iridium coated titanium anodes (often abbreviated as Ru-Ir/Ti anodes) are widely used in electrolysis processes due to their exceptional electrochemical performance, corrosion resistance, and stability. They combine the mechanical strength and corrosion resistance of titanium substrates with the high catalytic activity of ruthenium-iridium oxide coatings, making them a preferred choice in various industrial electrolysis applications
| Anode Type | Limitations | Advantages of Ru-Ir/Ti Anodes |
|---|---|---|
| Graphite Anodes | High corrosion rate, short lifespan, sludge formation | Longer life, no sludge, higher efficiency |
| Lead-based Anodes | Toxicity, poor stability in strong acids | Non-toxic, stable in aggressive environments |
| Platinum Anodes | High cost, prone to poisoning (e.g., by sulfides) | Lower cost, better resistance to poisoning |
Key Features
High Electrochemical Activity: The Ru-Ir oxide coating lowers the overpotential for critical reactions (e.g., chlorine evolution, oxygen evolution), improving electrolysis efficiency and reducing energy consumption.
Corrosion Resistance: Titanium’s inherent resistance to corrosion, combined with the stable oxide coating, allows the anode to operate in aggressive environments (e.g., high chloride concentrations, strong acids) without degradation.
Long Service Life: Under optimal conditions, these anodes can last 5–10 years in industrial electrolysis systems, far exceeding the lifespan of conventional anodes (e.g., graphite or lead-based anodes).
Stability in Wide Operating Range: They perform reliably across a range of temperatures (0–80°C), current densities (100–1000 A/m²), and pH levels (acidic to slightly alkaline).
Applications
1.Chlorine and Chlorate Production
Chlorine Evolution Reaction (CER): In brine electrolysis (e.g., chlor-alkali process), Ru-Ir/Ti anodes catalyze the oxidation of chloride ions (Cl⁻) to chlorine gas (Cl₂) , This is critical for producing chlorine, which is used in water treatment, chemical synthesis, and bleaching agents.
Chlorate Synthesis: In chlorate production, these anodes facilitate the formation of chlorate ions (ClO₃⁻) through successive oxidation reactions of Cl⁻ in alkaline brines.
2.Water and Wastewater Treatment
Electrochemical Disinfection: Ru-Ir/Ti anodes generate strong oxidants (e.g., Cl₂, HClO, O₃) during electrolysis, which effectively kill bacteria, viruses, and pathogens in drinking water or wastewater.
Electrocoagulation and Oxidation: They assist in breaking down organic pollutants (e.g., dyes, pharmaceuticals) in wastewater via advanced oxidation processes (AOPs), leveraging hydroxyl radicals (•OH) and other reactive species.
3.Swimming Pool Chlorination
As discussed earlier, Ru-Ir/Ti anodes are integral to pool chlorinators. They electrolyze salt (NaCl) in pool water to produce chlorine-based disinfectants (e.g., HClO), ensuring continuous water sanitization with minimal maintenance.
4.Metal Electrowinning and Electrorefining
In processes like copper or zinc electrowinning, these anodes are used to maintain stable oxygen evolution reactions (OER) at the anode, while metal ions are reduced and deposited at the cathode. The Ru-Ir coating resists corrosion from acidic electrolytes (e.g., sulfuric acid) used in these processes.
5.Electrolytic Production of Peroxides and Other Chemicals
They are employed in the synthesis of peroxodisulfates (e.g., Na₂S₂O₈) via electrolysis of sulfate solutions, where the anode catalyzes the oxidation of sulfate ions (SO₄²⁻) to peroxodisulfate (S₂O₈²⁻).
