titanium electrode for salt water electrolysis

In industrial electrolysis systems, choosing the right electrode material is critical to achieving high performance, stability, and cost efficiency. Among various electrode materials, the titanium electrode for salt water electrolysis has become one of the most reliable and efficient options for modern industries. With its excellent corrosion resistance, conductivity, and long service life, it is widely used in chlorine generation, seawater electrolysis, wastewater treatment, and hydrogen production.

What Is a Titanium Electrode for Salt Water Electrolysis?

A titanium electrode for salt water electrolysis is a specialized electrochemical component designed for use in saline environments. It serves as an anode or cathode in systems that convert sodium chloride (NaCl) and water into useful chemical products such as chlorine gas, sodium hydroxide, and hydrogen gas.

Technical Parameters of Titanium Electrodes

These parameters may vary based on design requirements, electrolyte composition, and system operating voltage.

How Does a Titanium Electrode Work in Salt Water Electrolysis?

The titanium electrode for salt water electrolysis plays a crucial role in splitting salt water into chemical products through electrochemical reactions.

The Basic Reaction

When an electric current passes through a salt water solution:

• At the anode (titanium electrode with MMO coating):

  2Cl−→Cl2+2e−2Cl^- \rightarrow Cl_2 + 2e^-2Cl−→Cl2​+2e−

  Chlorine gas is generated.

• At the cathode:

  2H2O+2e−→H2+2OH−2H_2O + 2e^- \rightarrow H_2 + 2OH^-2H2​O+2e−→H2​+2OH−

  Hydrogen gas and sodium hydroxide (NaOH) are produced.

This process is the foundation for chlor-alkali production, seawater chlorination, and hydrogen generation systems.

Key Advantages of Titanium Electrodes for Salt Water Electrolysis
1. Exceptional Corrosion Resistance

Titanium naturally forms a protective oxide layer that resists attack by chlorides and other oxidizing agents in salt water. The addition of MMO coatings further enhances its longevity.

2. High Electrochemical Efficiency

The titanium electrode for salt water electrolysis provides low overpotential and high current efficiency, reducing power consumption and operational costs.

3. Long Service Life

Thanks to the stable MMO or noble metal oxide coatings, these electrodes can operate continuously for 5–10 years depending on current density and operating conditions.

4. Environmentally Friendly

Unlike graphite or lead-based electrodes, titanium electrodes do not contaminate the electrolyte, making them ideal for eco-friendly water treatment and hydrogen generation.

5. Easy Maintenance and Replacement

The electrode’s modular structure allows for quick replacement and maintenance, minimizing system downtime.

Industrial Applications of Titanium Electrodes

The titanium electrode for salt water electrolysis has a wide range of industrial applications across multiple sectors:

1. Chlor-Alkali Industry

Used for the electrolysis of brine to produce chlorine, hydrogen, and sodium hydroxide—the cornerstone of many chemical manufacturing processes.

2. Seawater Chlorination Systems

Applied in marine, desalination, and cooling water systems to generate on-site chlorine for disinfection and biofouling control.

3. Hydrogen Production

In hydrogen generation units, titanium electrodes serve as durable anodes for long-term operation in saline or alkaline electrolytes.

4. Wastewater Treatment

Used for electrochemical oxidation of organic contaminants and electrocoagulation in industrial wastewater treatment systems.

5. Electroplating and Metal Finishing

Ensures consistent current distribution and reduced contamination in electroplating and surface finishing processes.

Titanium Electrodes in Seawater Chlorination Case 

In a coastal power plant cooling system, seawater is continuously circulated to remove heat. Biofouling from marine organisms often reduces flow efficiency and causes corrosion.

To address this, the plant adopted an on-site seawater electrolysis system using titanium electrodes coated with Ru–Ir MMO. The system generates sodium hypochlorite (NaOCl) directly from seawater, preventing fouling and corrosion.

Results:

Chlorine concentration: 0.8–1.0 ppm

Energy consumption reduced by 15%

Electrode lifespan exceeded 7 years

This case demonstrates the efficiency, reliability, and environmental benefits of titanium electrodes for salt water electrolysis.
