CO₂ Electroreduction to Ethylene: The Determining Role of the Cell and Electrode Design.

ABSTRACT: A series of copper-based electrocatalysts, selected from the literature for their high activity in the CO₂RR to ethylene, is compared under the same conditions, revealing a large discrepancy with the optimal results reported in the literature. A further detailed analysis of a copper oxide nanosheet electrocatalyst under different reaction conditions (cell configuration, i.e., liquid- vs gas-phase, membrane type, i.e., proton exchange membrane (PEM) vs anion exchange membrane (AEM), type of electrolyte, CO₂ mass transport under flow-field-enhanced conditions, and current density) reveals the dramatic role of cell and electrode configurations in determining selectivity. The Faradaic efficiency (FE) for ethylene production on copper oxide nanosheet electrocatalysts can v
