Product 1: Youveim® IrOx Chemically Plated Titanium Mesh (Stretched)
Product Description
The Youveim® IrOx Chemically Plated Titanium Mesh (Stretched) features a titanium mesh coated with iridium oxide, known for its high catalytic efficiency in oxygen evolution reactions (OER). The stretched mesh has larger pore sizes and thicker wire diameters, offering a rugged structure with a significant surface area exposed to the electrolyte.
Key Features
- Pore Size & Thickness: Large pore sizes and thicker wires allow efficient flow of electrolyte and gas release.
- IrOx Coating: The chemically plated iridium oxide layer provides exceptional catalytic activity, corrosion resistance, and longevity.
- Durable Construction: The stretched titanium mesh provides a balance of mechanical strength and electrical conductivity.
Advantages for OER Applications
- In Water Electrolyzer:
- Large O₂ bubbles are easily released from the anode, reducing bubble overpotential.
- Enhanced durability supports high current densities for extended operational periods.
- Large pores reduce resistance in high-flow systems, making it suitable for industrial-scale water electrolysis.
- In CO₂ Electrolyzer:
- Larger pores and durability are beneficial in handling the typically more aggressive environment of CO₂ electrolysis.
- IrOx catalysis is advantageous for stabilizing anodes exposed to carbonates or bicarbonates, preventing degradation in the harsh environment of CO₂ electrolyzers.
Disadvantages
- In Water Electrolyzer:
- Large bubble formation can lead to less uniform gas distribution in applications requiring dense gas release.
- Limited surface area compared to fine meshes can result in slightly lower catalytic activity.
- In CO₂ Electrolyzer:
- Larger pores may limit fine control over CO₂/O₂ bubble management, impacting applications where close bubble control is essential.
- Larger bubbles may lead to inefficiencies in systems where gas recapture is essential for reaction optimization.
Product 2: Youveim® IrOx Chemically Plated Titanium Mesh (Woven)
Product Description
The Youveim® IrOx Chemically Plated Titanium Mesh (Woven) is a finely woven titanium mesh with an IrOx coating, providing high surface area and catalytic efficiency. The mesh design, characterized by small pore sizes and thin wires, supports the dense release of gas bubbles, ideal for reactions where precise gas management is key.
Key Features
- Fine Mesh Design: Small pore sizes and thin wires maximize surface area, enhancing catalytic contact with the electrolyte.
- Dense IrOx Coating: Provides stable, long-lasting catalytic properties that are particularly useful in maintaining efficiency under high electrolyte flow conditions.
- Enhanced Surface Interaction: High surface area increases reaction efficiency and gas bubble dispersion.
Advantages for OER Applications
- In Water Electrolyzer:
- Produces small, dense O₂ bubbles, ensuring close gas management and a more homogeneous electrolyte distribution.
- The fine mesh design optimizes interaction between the anode and electrolyte, potentially increasing reaction rates.
- Ideal for low-flow, high-efficiency applications where compact bubble formation supports efficient gas saturation.
- In CO₂ Electrolyzer:
- Enhanced surface area supports stable CO₂ conversion, optimizing reaction efficiency by improving contact between the anode and CO₂ in solution.
- Smaller bubbles contribute to controlled release, reducing crossover effects and improving overall system stability in CO₂ electrolysis.
- Fine pore structure is beneficial for maintaining stable reaction conditions in compact CO₂ electrolyzer setups.
Disadvantages
- In Water Electrolyzer:
- Smaller pores may increase resistance in systems where high flow and gas release are required.
- Dense bubble formation may lead to gas trapping, which can impact overall current efficiency at higher current densities.
- In CO₂ Electrolyzer:
- Higher surface area and smaller pores may be more prone to clogging or fouling in systems with impurities in the CO₂ stream.
- The small bubbles produced may increase gas-phase resistance in applications that require high throughput, reducing overall efficiency in large-scale operations.
