Product Overview
DiffuCarb™ E400 · Ag · Carbon Paper Cathode · MEA CO₂ Electrolyzer
DiffuCarb™ E400 Ag - Carbon Paper Cathode Electrode for MEA CO₂ Electrolyzers is a cathode material for CO₂ electroreduction (CO₂RR), primarily used to convert CO₂ to CO in membrane-electrode-assembly electrolyzers.
The electrode combines an Ag catalyst with a porous carbon paper substrate. Ag provides the electrocatalytic interface required for CO₂-to-CO conversion, while carbon paper provides electronic conduction, gas transport and mechanical support. According to the supplied product description, the structure is designed to balance catalytic activity, CO selectivity, electrical conductivity and electrode stability.
Ag Catalyst
Provides the primary cathodic electrocatalytic interface for CO₂-to-CO conversion.
CO₂RR Cathode
Designed for the cathode side of MEA CO₂ electrolyzers used in CO₂ conversion research.
Porous Carbon Paper
Provides electronic conduction, reactant transport and mechanical support.
CO Product Positioning
According to the current product description, CO is the primary target product.
Structure & Key Features
Ag catalyst layer + porous carbon paper substrate
Electrocatalytic Properties of Silver
According to the supplied product description, Ag promotes CO₂ adsorption, electron transfer and CO formation, enabling CO₂-to-CO reduction at relatively low overpotential and providing high selectivity toward CO.
Conductive & Mass-Transfer Carbon Paper
Carbon paper provides electrical conductivity, mechanical strength and a porous structure. It increases the electrode/reactant contact interface and supports electron conduction and gas transport under higher current-density operation.

CO₂-to-CO Reduction Process
CO₂ adsorption · electron transfer · CO desorption
CO₂ Adsorption
CO₂ molecules first reach and adsorb on the Ag catalytic interface, creating reaction sites for subsequent electron transfer.
Electron Transfer & Reduction
The Ag catalyst promotes electron transfer to CO₂, driving electrochemical reduction toward CO.
CO Desorption
The generated CO desorbs from the catalyst surface and leaves the electrode interface, freeing catalytic sites for continued reaction.
Advantages & Application Potential
Selectivity · conversion efficiency positioning · cost · CCU applications
CO Selectivity
The supplied product material positions the electrode as a highly selective Ag cathode for CO₂-to-CO conversion.
High Faradaic Efficiency Positioning
The supplied material mentions Faradaic efficiency of about 96% or higher; actual results depend on test and operating conditions.
Catalyst Cost Advantage
Compared with Au- or Pt-based catalyst systems, Ag offers certain advantages in cost and material availability.
CCU Application Potential
Suitable for CO₂ electrolysis, CO production, carbon capture and utilization research, and scale-up validation.
Experimental Validation & Long-Term Operation
Stability · selectivity · industrial scale-up potential
Long-Term Stability
The supplied product description states that Ag-carbon paper electrodes maintain relatively stable electrocatalytic activity and selectivity during extended electrolysis.
Broad Operating-Condition Research
Suitable for CO₂RR electrolysis studies across different voltages, current densities and MEA configurations.
Industrial Scale-Up Potential
Can be used for research and scale-up validation of large-area CO₂ electrolysis, CO production and CCU processes.
