Platinized Titanium Fiber Paper – Vacuum Thermal Reduction

Description

In advanced electrolyzers and electrochemical energy systems, the choice of electrode diffusion layer materials directly affects efficiency, stability, and lifetime. Platinized Titanium Fiber Paper – Vacuum Thermal Reduction is made from high-purity sintered titanium fibers. The fibers are first acid-washed to remove surface oxides and impurities, then platinum-coated via vacuum thermal reduction, ensuring a uniform and robust Pt layer.

This dual-process approach delivers enhanced electrochemical activity, superior catalytic performance, and outstanding corrosion resistance, making it ideal for anode diffusion layers (PTL) in electrolyzers and high-performance battery current collectors.

🔑 Dual-Process Advantages

🌟 Acid Wash Benefits

• Cleaner, more active surface – removes oxides and impurities to enhance electrochemical activity.
• Uniform, stable oxide layer – thin and even passivation layer improves electron conduction and catalyst adhesion.
• Stronger catalyst binding – ideal for loading Pt, Ir, Ru, and other catalysts.
• Enhanced corrosion resistance – maintains stable performance during long-term operation.
• Lower onset potential – reactions initiate faster, improving energy efficiency.

🌟 Platinum Coating (Vacuum Thermal Reduction) Benefits

• Adjustable Pt loading (0.1–10 mg/cm²) – tailored for both research and industrial applications.
• Selectable Pt layer thickness (0.5 / 1 / 2 μm, customizable) – uniform coverage for excellent conductivity and catalytic performance.
• Vacuum thermal reduction – strengthens Pt-titanium adhesion, boosting long-term stability and corrosion resistance.
• High catalytic efficiency – accelerates oxygen/hydrogen evolution reactions, improving hydrogen production efficiency and energy utilization.

⚡ Core Titanium Fiber Paper Advantages

• Excellent oxidation resistance – stable under strong oxidative conditions, unlike carbon paper which decomposes to CO₂.
• High conductivity – continuous sintered fibers ensure even current distribution.
• High porosity (50–70%) – facilitates gas and electrolyte transport, enhancing reaction efficiency.
• Flexible and customizable – supports different thicknesses, fiber lengths, and dimensions.
