platinized titanium anode

Platinized Titanium Anodes are high-performance insoluble electrodes designed for electrochemical water treatment and electrolyzed functional water systems. They consist of a titanium substrate, typically TA1/Gr1 titanium, coated with a controlled layer of platinum (Pt).

The platinum coating provides excellent electrocatalytic activity and corrosion resistance, enabling stable electrode performance during electrolysis. Depending on the electrolyte composition, electrode configuration, and operating conditions, platinized titanium anodes can be used in systems for electrolyzed acidic and alkaline water, hydrogen-rich water generation, cleaning, disinfection, and other electrochemical water treatment applications.

Working Principle

During electrolysis, direct current is applied between the anode and cathode through an electrolyte-containing water solution.

At the electrodes, electrochemical reactions take place and water is separated into different streams or reaction zones according to the design of the electrolytic cell.

At the anode, oxidation reactions occur, while reduction reactions take place at the cathode. Depending on the electrolyte and operating conditions, the process can generate hydrogen, oxygen, hydrogen ions, hydroxide ions, and other electrochemically active species.

The platinum coating serves as an electrocatalytic surface, facilitating electrode reactions and providing stable electrochemical performance.

The actual composition and properties of the generated water depend on factors such as electrolyte composition, current density, electrode spacing, water quality, temperature, and electrolysis time.

Key Features

High Electrocatalytic Activity

Platinum provides excellent catalytic activity for a wide range of electrochemical reactions, making Pt-Ti electrodes suitable for compact and high-efficiency electrolysis systems.

Excellent Corrosion Resistance

The titanium substrate combined with the platinum coating provides good resistance to corrosion in appropriately controlled acidic and alkaline operating environments.

Stable Electrochemical Performance

A properly prepared Pt coating provides a stable active surface and reliable electrical performance during continuous electrolysis.
