C2CAT Catalysts Applied in CO₂-to-Ethanol Electrochemical Process
C2CAT Cu-based catalysts have been utilized in a recently published open access peer-reviewed study investigating electrochemical CO₂ reduction to ethanol in a continuous flow-cell system, click here to access the article.
The study evaluated commercial C2CAT materials including 5% Cu/ZrO₂, 10% Cu/SiO₂, and ZnO-doped Cu/SiO₂ formulations (2% and 3.5% ZnO). Gas diffusion electrodes were fabricated using these catalysts and tested under controlled current densities in a three-electrode flow-cell configuration.
Among the materials studied, the 10% Cu/SiO₂ catalyst achieved a Faradaic efficiency of up to 96% for ethanol at −3 mA·cm⁻² demonstrating high selectivity toward C₂ products under optimized conditions. Structural and surface analyses (including XPS and SEM) highlighted the role of Cu oxidation states, support interactions, and ZnO modification in influencing C–C coupling pathways and overall performance.
The work confirms the suitability of C2CAT catalyst systems for structured gas diffusion electrode configurations and advanced CO₂ electroreduction research, particularly where selectivity toward higher-value C₂ products such as ethanol is targeted.
The catalysts used in this study are available through the C2CAT online store for research and development purposes. Researchers interested in replicating or extending this work can access the same commercial-grade materials directly.
