Titanium Pt Electrode for Water Ionizer

A Titanium Pt (platinum-coated titanium) electrode is a functional electrode used in water ionizers and electrolysis water machines to generate alkaline and acidic ionized water through electrochemical reaction.

It is made by using high-purity titanium (Gr1 or Gr2) as the substrate and coating it with a thin layer of platinum (Pt) through electroplating or thermal deposition processes. This structure combines the mechanical strength and corrosion resistance of titanium with the excellent electrocatalytic performance of platinum.

Working Principle in Water Ionizers

During electrolysis, water is separated into:

• Alkaline ionized water (cathode side)

• Acidic ionized water (anode side)

At the same time, several active substances are generated in the system, such as:

Ozone (O₃)

Hydrogen peroxide (H₂O₂)

Hypochlorous acid (HClO)

Because of these strong oxidizing conditions and frequent polarity switching, the electrode must have excellent stability and corrosion resistance.

Key Advantages of Titanium Pt Electrodes

1. Excellent electrical conductivity
   Ensures efficient electrolysis and stable ionization performance.

2. Strong corrosion resistance
   Titanium substrate resists acidic and oxidizing environments, while platinum coating prevents surface degradation.

3. High electrocatalytic activity
   Platinum significantly improves reaction efficiency, reducing energy consumption during electrolysis.

4. Long service life
   Typically operates stably for 5–10 years depending on working conditions.

5. Strong coating adhesion
   Sandblasted titanium surface ensures firm bonding between Pt layer and substrate, preventing large-area peeling even under long-term use.

6. Stable water quality output
   Produces consistent alkaline and acidic water with improved pH efficiency under the same power input.

Application

Titanium Pt electrodes are widely used in:

Household water ionizers
