This Ruthenium-Iridium Coated Titanium Anode (Ru-Ir/Ti MMO Electrode) is a high-performance, dimensionally stable anode designed for applications requiring efficient chlorine evolution. The 100x100x1mm size is ideal for laboratory research, bench-scale testing, and as a replacement component for small to medium-sized electrolytic systems.
Why Choose This Electrode?
1. High Efficiency Chlorine Evolution
The mixed metal oxide (MMO) coating combines ruthenium and iridium—two of the most effective catalysts for the chlorine evolution reaction (CER). This results in:
Low overpotential: Less energy required to drive the reaction
High current efficiency: More of your electricity goes toward useful work
Cost savings: Lower operating costs over the life of the electrode
2. Stop Contaminating Your Electrolyte & Cathode Products
Traditional anodes made of graphite or lead slowly dissolve during operation. This creates two serious problems:
Contaminated electrolyte: Dissolved impurities ruin expensive electrolyte baths, forcing frequent replacement
Compromised cathode products: Those same contaminants deposit onto your cathode, degrading product quality and causing rejected batches
Our insoluble Ru-Ir/Ti anode eliminates these risks entirely. The precious metal oxide coating does not dissolve during electrolysis, ensuring:
Your electrolyte stays pure, batch after batch
Only the intended metal deposits on your cathode
No unexpected impurities, no rejected batches
3. Can Also Function in Oxygen Evolution
While this electrode is optimized for chloride-containing environments (seawater, brine), it can also operate in oxygen-evolving systems such as sulfate solutions.
Important: Long-term operation in pure oxygen evolution environments will reduce the electrode's lifespan. For applications requiring extended oxygen evolution, we recommend our Iridium-Tantalum (Ir-Ta) coated anodes.
