What is a Titanium Based Oxide Coated Electrode?

In the modern electrochemical industry, the demand for efficient, durable, and eco-friendly electrode materials has grown dramatically. One of the most widely used and advanced solutions is the Titanium based oxide coated electrode. Known for its excellent conductivity, corrosion resistance, and long service life, this electrode is widely applied in industries such as electroplating, wastewater treatment, chlor-alkali production, and cathodic protection.

What is a Titanium Based Oxide Coated Electrode?

A Titanium based oxide coated electrode is a type of Dimensionally Stable Anode (DSA), where a titanium substrate is coated with noble metal oxides such as ruthenium oxide, iridium oxide, or mixed metal oxides.

Substrate: Pure titanium plate, mesh, or tube

Coating layer: Metal oxide compounds with catalytic and conductive properties

Function: Provides high electrochemical performance while resisting corrosion in harsh electrolytes

This unique combination ensures that Titanium based oxide coated electrodes maintain excellent stability, making them a cost-effective and reliable choice for long-term industrial use.

Key Features of Titanium Based Oxide Coated Electrode
1. Excellent Corrosion Resistance

Titanium naturally forms a stable oxide layer, and when combined with noble metal oxide coatings, the electrode achieves outstanding resistance against acid, alkali, and salt corrosion.

2. High Conductivity and Low Energy Consumption

The oxide coating provides superior conductivity, ensuring that Titanium based oxide coated electrodes minimize energy loss during electrolysis, leading to reduced operating costs.

3. Long Service Life

Thanks to their stable oxide coating, these electrodes can last several years, even under extreme industrial conditions, reducing replacement frequency.

4. Environmental Benefits

Unlike traditional electrodes, Titanium based oxide coated electrodes avoid heavy metal pollution and provide a more eco-friendly solution for industries focused on sustainability.

Working Principle of Titanium Based Oxide Coated Electrode

The Titanium based oxide coated electrode operates as an anode in electrochemical processes. When electric current passes through the electrode in an electrolyte solution, the oxide coating catalyzes reactions such as chlorine evolution, oxygen evolution, or hydrogen suppression.

Chlorine Evolution Reaction (CER): Widely used in chlor-alkali industries

Oxygen Evolution Reaction (OER): Crucial for wastewater treatment and water electrolysis

Selective Catalysis: Tailored coatings allow specific reactions for different industries

This flexibility in design and coating composition is one of the reasons Titanium based oxide coated electrodes have become a dominant solution in electrochemistry.

Industrial Applications of Titanium Based Oxide Coated Electrode
1. Electroplating Industry

The electrode ensures uniform current distribution and stable performance, improving plating quality and reducing energy costs.

2. Wastewater Treatment

Titanium based oxide coated electrodes are widely used in advanced oxidation processes (AOPs) to degrade organic pollutants and disinfect industrial wastewater.

3. Chlor-Alkali Production

In chlorine and caustic soda production, these electrodes efficiently catalyze the chlorine evolution reaction, replacing traditional graphite or lead-based electrodes.

4. Cathodic Protection

Offshore structures, pipelines, and storage tanks rely on Titanium based oxide coated electrodes for cathodic protection, preventing metal corrosion.

5. Electrolytic Synthesis

They are applied in electrolytic production of persulfates, hypochlorites, and other chemicals, offering high efficiency and durability.

Technical Parameters of Titanium Based Oxide Coated Electrode

Base material: Pure titanium (Grade 1 or Grade 2)

Coating composition: RuO₂, IrO₂, Ta₂O₅, or mixed metal oxides

Shape: Plate, mesh, tube, rod, or custom design

Coating thickness: 2–10 μm (adjustable by application)

Current density range: 1000–5000 A/m²

Service life: 2–10 years depending on electrolyte and usage conditions

These parameters can be customized according to specific customer requirements, making Titanium based oxide coated electrodes highly versatile.
