1. Substrate and Coating Composition
Titanium Substrate: Industrial pure titanium (TA1/TA2) is used, relying on its 5–10 nm thick TiO₂ passive film for corrosion resistance and stability.
Iridium-Based Coatings:
Systems: IrO₂-Ta₂O₅, IrO₂-RuO₂, or pure IrO₂, made by thermal decomposition (400–500°C sintering) or pulsed electrodeposition, 5–20 μm thick.
Function: IrO₂ reduces OER overpotential (≤ 300 mV @ 100 mA/cm²), while Ta₂O₅/RuO₂ improves adhesion and durability.
2. Surface Modification Techniques
Nanostructuring: Anodization creates TiO₂ nanotube arrays with IrO₂, tripling surface area and increasing active sites by 40%.
Gradient Coating: A 5 μm Ta₂O₅ base layer boosts bonding, topped with 10 μm IrO₂, reducing noble metal use by 20%.
Advantages in Industrial Applications
Application
Petrochemical Wastewater: Degrades benzene, toluene, and xylene (BTX) with >90% removal efficiency in 2–4 hours.
Textile Dye Wastewater: Breaks down azo dyes (e.g., methyl orange) via •OH oxidation, achieving color removal >95%.
Landfill Leachate: Removes COD (chemical oxygen demand) from 5,000–10,000 mg/L to <500 mg/L via combined direct/indirect oxidation.

Production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
