Unlocking CO₂ Reduction Potential with DiffuCarb® E300T
IrO₂ / Hydrophobic Interface / F200T Carbon Paper / CO₂RR Anode
As carbon-neutral and carbon-utilization technologies continue to develop, CO₂ reduction reactions (CO₂RR) require electrode systems that combine catalytic activity with effective management of water and gas transport. DiffuCarb® E300T is designed as an IrO₂-carbon paper electrode with a hydrophobic interface for use on the anode side of CO₂ electrolysis cells.
The electrode integrates an IrO₂ catalytic layer, a hydrophobic interface, PTFE / Teflon binder and a conductive carbon paper substrate. This architecture is intended to support oxidation-side electrocatalysis while maintaining gas diffusion, water management, mechanical integrity and electrical conduction.
IrO₂ Catalytic Layer
Provides oxidation-side electrocatalytic activity for CO₂ electrolysis anode operation.
Hydrophobic Interface
Helps manage liquid water and maintain more stable gas-transfer pathways.
Carbon Paper Substrate
Provides electrical conduction, porous transport pathways and mechanical support.
CO₂ Electrolysis Focus
Developed for laboratory and scale-up research involving CO₂ conversion and electrolysis systems.

IrO₂ Catalytic Layer
IrO₂ is used as the oxidation-side catalyst layer. The supplied product description positions it as a highly stable electrocatalyst for the anode environment in CO₂ electrolysis cells.
Hydrophobic Interface
The hydrophobic interface is intended to reduce persistent liquid accumulation at the electrode surface, supporting gas transport and helping minimize flooding-related performance loss.
PTFE / Teflon Binder
PTFE is used to enhance hydrophobicity while also contributing chemical stability and mechanical cohesion to the catalyst-coated electrode structure.
Carbon Paper Substrate
The carbon paper substrate provides electronic conduction, porous transport channels and structural support for the IrO₂ catalytic layer.
