What is an electrolytic ozone electrode?

An electrolytic ozone electrode is a titanium-based catalytic electrode used for generating ozone via water electrolysis. It typically uses TA1/TA2 commercially pure titanium as the substrate, coated with a tin-antimony-based catalytic layer optimized for ozone-generating reactions, enabling water oxidation at the anode to produce ozone.

In an electrolytic ozone generation system, the electrode must work in coordination with the electrolytic cell, power supply, water flow path, and control system. As water passes through the electrolytic cell, the catalytic coating on the anode surface facilitates electrochemical reactions that generate ozone, which then dissolves into the water to form oxidizing ozone-enriched water.

These electrodes are ideal for compact, modular devices requiring on-site ozone water generation-such as ozone water machines, oral irrigators, food cleaning appliances, smart washing machines, air deodorizing and purification units, and certain water disinfection systems.

How does an electrolytic ozone electrode generate ozone water?

The electrolytic ozone electrode generates ozone at the anode through water electrolysis. When water enters the electrolytic cell, the catalytic coating on the anode surface drives an oxidation reaction under direct current, converting water molecules into ozone that dissolves into the water to form ozone-enriched water.

A common anodic reaction can be expressed as: 3H₂O - 6e⁻ → O₃ + 6H⁺

The generated ozone exhibits strong oxidizing capability, enabling microbial control in water, odor oxidation, partial organic compound degradation, and water purification. For ozone water machines, oral irrigators, smart washing machines, food cleaning devices, and small disinfection modules, electrolytic ozone generation is better suited for on-demand, in-device production without requiring additional large-scale ozone dosing systems.

Ozone generation occurs at the anode surface

In electrolytic ozone systems, ozone is primarily generated at the anode surface. Factors such as electrode coating, electrode area, inter-electrode spacing, current density, water quality, flow rate, and electrolytic cell design all influence the stability of ozone water output.

Therefore, selecting an electrolytic ozone electrode should not be based solely on physical dimensions; it must also account for the actual water flow path, flow rate, target ozone concentration, and operational mode of the equipment.

Oxidation effects in ozone water

Once dissolved in water, ozone can directly participate in oxidation reactions or further form reactive species with oxidizing capacity, helping devices achieve auxiliary disinfection, deodorization, decolorization, and organic matter oxidation.

In applications such as drinking water treatment, food cleaning, secondary water supply, medical water treatment, and certain wastewater scenarios, the effectiveness of ozone water typically depends on ozone concentration, contact time, water quality conditions, and equipment design.

Available electrode shapes

Different ozone water equipment varies in electrolytic cell space, water flow path, installation method, and target ozone concentration, leading to diverse electrode shape requirements. Chalco Titanium offers titanium mesh, titanium plate, sheet-type, and custom electrode assemblies to match various ozone water generation equipment types.

Difference between electrolytic ozone electrodes and chlorine-generating electrodes

Both electrolytic ozone electrodes and chlorine-generating electrodes are titanium-based electrodes used in water treatment, but they differ in reaction objectives, applicable media, coating systems, and equipment purposes. Selection should not rely solely on physical dimensions; it is essential first to confirm whether the device aims to produce ozone water or chlorine-based disinfectants.

Comparison item	Electrolytic ozone electrode	Chlorine-generating electrode
Primary product	Ozone (O₃)	Chlorine, hypochlorous acid, or sodium hypochlorite
Main reaction objective	Electrolyze water to generate ozone water	Electrolyze chloride-containing water to generate chlorine-based disinfectants
Typical coating type	Tin-antimony catalytic coating	Ru-Ir, RuO₂, or other chlorine-evolving coatings
Common media	Tap water, treated water, project-specific water sources	Brine, swimming pool water, seawater, or chloride-containing water
Typical equipment	Ozone water machines, oral irrigators, food cleaning devices, air deodorizers, drinking water treatment systems	Sodium hypochlorite generators, hypochlorous acid generators, swimming pool disinfection systems, seawater electrolytic chlorination units
Primary applications	Cleaning, deodorization, auxiliary disinfection, oxidative water treatment	Chlorination disinfection, sodium hypochlorite production, swimming pool sanitation, marine antifouling
Selection focus	Target ozone concentration, flow rate, water quality, electrode area, electrolytic cell design	Salt concentration, available chlorine output, current density, polarity reversal method, scale resistance

Selection tip:

If the device is intended to generate ozone water on-site for cleaning, deodorizing, disinfection assistance, or oxidative purification, electrolytic ozone electrodes should be selected. If the device is designed to electrolyze chloride-containing water to produce hypochlorous acid, sodium hypochlorite, or other chlorine-based disinfectants, chlorine-generating electrodes should be chosen.
