In the field of electrochemical processes, titanium electrode for electrolysis has become an essential component for achieving efficiency, durability, and environmental sustainability. Known for their superior corrosion resistance, high electrical conductivity, and long service life, titanium electrodes play a vital role in numerous industrial electrolysis applications—from water treatment and metal refining to hydrogen production and electroplating.
What is a Titanium Electrode for Electrolysis?
A titanium electrode for electrolysis is a conductive component made primarily from titanium substrate, coated with active catalytic materials such as ruthenium oxide (RuO₂), iridium oxide (IrO₂), or platinum (Pt). These coatings improve the electrode’s catalytic activity and corrosion resistance, ensuring stable performance even in harsh electrolytic environments.

Advantages of Using Titanium Electrode for Electrolysis
Choosing a titanium electrode for electrolysis provides several key benefits compared to traditional graphite or steel electrodes.
1. Superior Corrosion Resistance
The noble metal oxide coatings protect the titanium substrate even under aggressive chemical conditions, extending electrode lifespan.
2. High Catalytic Efficiency
The electrode surface maintains a high level of catalytic activity, minimizing voltage drop and reducing energy consumption.
3. Stable Electrochemical Performance
Titanium electrodes exhibit excellent current distribution, ensuring consistent product quality in electrochemical reactions.
4. Low Maintenance Cost
With long service life and minimal degradation, titanium electrodes reduce maintenance frequency and downtime.
5. Customizable Design
Manufacturers can produce titanium electrodes in different shapes—mesh, plate, rod, or tube—based on specific equipment or industry needs.
Application fields of titanium electrodes for electrolysis
1. Water Treatment and Electrochlorination
Titanium electrodes are used in electrochlorination systems to produce sodium hypochlorite from seawater or brine. These systems are essential for:
Disinfecting drinking water
Sterilizing swimming pools
Desalination plants
Marine ballast water treatment
2. Metal Electroplating and Electrorefining
In the electroplating industry, titanium electrodes serve as insoluble anodes, providing uniform current distribution for high-quality metal coatings such as copper, nickel, and chromium.
3. Hydrogen Production by Electrolysis of Water
With the growing demand for green hydrogen, titanium electrodes for electrolysis have become indispensable in alkaline and PEM electrolyzers. Their stability and low overpotential make them ideal for continuous hydrogen generation.
4. Wastewater Treatment
Titanium electrodes are effective for electro-oxidation, COD removal, and decolorization of industrial wastewater. They are especially useful in treating wastewater from:
Textile dyeing
Petrochemical plants
Electroplating factories
5. Electrochemical Synthesis
Used in producing various chemicals (e.g., perchlorates, chlorates, and hypochlorites), titanium electrodes help improve process yield and energy efficiency.
Titanium Electrode for Electrolysis in Action Case
1: Seawater Electrochlorination Plant
A coastal water treatment facility in Southeast Asia adopted Ru-Ir oxide-coated titanium electrodes to generate sodium hypochlorite for sterilization. The system operated continuously for over five years without noticeable degradation, reducing chemical purchase costs by 35%.
2: Hydrogen Production Project
A renewable energy company in Europe implemented Pt-coated titanium electrodes in a proton exchange membrane (PEM) electrolyzer. The system achieved high hydrogen purity (>99.999%) and reduced energy consumption by 20% compared to conventional electrodes.
3: Electroplating Wastewater Treatment
In a Chinese electroplating plant, titanium electrodes for electrolysis were used for COD reduction and metal ion recovery, significantly improving effluent quality and meeting strict environmental discharge standards.
