The electrodeposition of Cu and Zn onto bare CuZn mesh supports offers a straightforward method for fabricating novel electrodes electrochemical CO2 reduction (EC CO2R). This study evaluates the performance these modified by assessing their Faradaic efficiency (FE) under various conditions including different electrolytes, concentrations, applied potentials, recycling effects, Nafion treatment. products were categorized into several groups: C1 gaseous (CO CH4), C2 (C2H4 C2H6), C3,4 hydrocarbons, major C1/C2/C3 liquid (formate, ethanol, propanol), minor (methanol, acetate, acetaldehyde, isopropanol). We evaluated dynamic FE variations experimental conditions. production C2+ hydrocarbons through EC CO2R was found to be analogous conventional Fischer–Tropsch synthesis, highlighting pivotal roles *CO *CHx intermediates. study's insights C1, C2, C3+ product chemistry aid in further development Cu-based electrocatalysts.

CO₂ Electroreduction to Long‐Chain Hydrocarbons on Cobalt Catalysts

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 24, 2024

Abstract Renewable‐powered electrocatalytic CO 2 conversion to long‐chain hydrocarbons represents a sustainable path produce chemicals and fuels. However, recently discovered systems still lack C–C coupling capabilities required yield longer, more valuable carbon chains. This study reports cobalt catalysts with focus on Co 3 O 4 ‐derived material for the selective of C 1 –C 7 hydrocarbons, following an Anderson–Schulz–Flory distribution. The obtained chain growth probability ( α ) 0.54 substantially exceeds that any other known electrocatalyst, which ranged from 0.2 0.4. Detailed in situ characterization simulations indicated Co‐Co interfaces, formed during electrolysis, are active sites promote enhanced growth. To prevent overreduction causes deactivation these interfacial sites, electrode is exposed intermittent short reoxidation cycles electrolysis. Consequently, catalyst regained its oxidic phase ability form hydrocarbons. Overall, this opens new frontiers one‐step into multi‐carbon products suggests exploration metal–metal oxide interfaces as promising strategy further progress.
