Product Introduction
Platinum is one of the most stable and catalytically active electrode materials used in electrochemical industries. It is widely applied in:
Electroplating
Electrolytic synthesis
Electrochemical wastewater treatment
Fuel cells
Hydrogen peroxide production
Ammonium persulfate production
Water electrolysis systems
Platinum electrodes are characterized by:
Excellent corrosion resistance
High catalytic activity
High oxygen evolution potential
Low hydrogen evolution overpotential
Stable electrochemical performance
In most acid environments-including hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, phosphoric acid, and various electrolyte solutions-platinum shows outstanding chemical stability.
Advantages
Although platinum performs exceptionally well, it has two major limitations:
High cost
Scarcity of platinum resources
Using solid platinum electrodes in industrial-scale systems is economically impractical, especially for large-area electrodes.
To reduce cost while maintaining platinum's electrochemical performance, titanium-based platinum anodes have been developed.
Titanium provides:
High mechanical strength
Excellent corrosion resistance
Lightweight structure
Strong dimensional stability
By coating platinum onto a titanium substrate, the electrode achieves:
Reduced platinum consumption
Lower production cost
Maintained catalytic efficiency
Improved mechanical durability
Limitations of Conventional Platinum Electroplating
Traditional titanium platinum anodes typically use a platinum salt electroplating process.
Common issues include:
High plating solution consumption
High production cost
Weak bonding strength of the platinum layer
Risk of coating peeling under long-term high current operation
Advanced coating technologies significantly improve adhesion and extend service life.
Performance Advantages
Excellent stability in electrolysis functional water systems
Uniform current distribution
Strong coating adhesion
Long-term corrosion resistance
Low energy consumption
Stable overpotential
Application in Functional Water Electrolysis
Platinum-coated titanium anodes are widely used in:
Alkaline ionized water systems
Acidic oxidation water systems
Hydrogen-rich water generation
Disinfection water systems
Electrolyzed water sterilization equipment
Their high oxygen evolution potential ensures stable electrolysis while maintaining water purity.
