In salt water electrolysis—whether for chlorine production, sodium hypochlorite synthesis, or seawater treatment—DSA titanium electrodes serve as the anode, driving the critical oxidation of chloride ions (Cl-)):2Cl-＝Cl2↑+2e- The chlorine gas generated further reacts with water to form hypochlorous acid (HClO) or hypochlorite ions (ClO-), key oxidizing agents for disinfection or chemical synthesis. Unlike traditional anodes (e.g., graphite), DSA titanium electrodes maintain their shape and performance over time, ensuring consistent reaction efficiency and reducing maintenance needs.
Titanium Substrate: High-purity titanium (GR1/GR2) provides a robust, corrosion-resistant base that withstands the aggressive, high-chloride environment of salt water. Its excellent conductivity ensures efficient current transfer to the coating.
Mixed Metal Oxide (MMO) Coating: The defining feature of DSA electrodes, the coating is typically a blend of noble metal oxides such as ruthenium oxide (RuO₂), iridium oxide (IrO₂), and tantalum oxide (TaO₂). This formulation:
Lowers the overpotential for chloride oxidation, reducing energy consumption.
Resists corrosion from chlorine and acidic byproducts, extending electrode life.
Enhances selectivity for chlorine evolution over unwanted reactions (e.g., oxygen evolution), maximizing target product yield.
Advantage
High Current Efficiency: Achieves 90–95% current efficiency for chlorine evolution, meaning most of the electrical energy is converted into the desired reaction rather than waste heat.
Stable Operating Parameters: Performs reliably at current densities of 1000–3000 A/m² and cell voltages of 2.5–4.0 V, suitable for both small-scale and industrial electrolyzers.
Long Service Life: In typical salt water electrolysis conditions, lifespan ranges from 3–7 years, far exceeding graphite anodes (6–12 months) or lead-based anodes (1–2 years).
Broad Compatibility: Works in brine (NaCl solutions), seawater, and brackish water, adapting to varying salinity levels (1–35 g/L Cl⁻) without performance degradation.
Applications in Salt Water Electrolysis
Chlor-Alkali Industry:
Central to the electrolysis of brine (saturated NaCl) for producing chlorine gas, sodium hydroxide (NaOH), and hydrogen. DSA electrodes here reduce energy use by 10–15% compared to older technologies.
Sodium Hypochlorite Generation:
Used in on-site electrolyzers to produce sodium hypochlorite (NaClO) from dilute salt water, a critical disinfectant for water treatment (municipal water, swimming pools, wastewater).
Seawater Treatment:
Integrated into marine systems (e.g., ship ballast water, offshore platforms) to electrolyze seawater, generating biocides that prevent biofouling and microbial growth.
Desalination Auxiliary:
Helps control membrane fouling in desalination plants by electrolyzing brine waste to produce chlorine, which sanitizes feed water and reduces organic contamination.
