Electrochemical carbon monoxide reduction (COR) is an important link between the electrochemical CO2-to-CO and renewable production of C2+ chemicals. Along with development catalyst materials for selective efficient COR, it imperative to optimize electrolysis conditions cell parameters efficiently reduce CO at industrially relevant current density produce concentrated product streams. This study focuses on understanding fundamental differences in reaction selectivity during when same Cu was used three different configurations, namely, microfluidic, hybrid anode zero-gap, zero-gap electrolysers. In all cases, ethylene, acetate, ethanol, propanol formation confirmed densities (0.5–––1.2 A cm−2) reasonable voltages, albeit subtle differences. The local chemical environment electrode/electrolyte interface very each configuration leading distribution crossover anode. stresses importance architecture implies that comparing catalytic activity a studied configurations can lead inconsistent conclusions.

Abstract The electrocatalytic conversion of CO 2 into valuable multi‐carbon (C 2+ ) products using Cu‐based catalysts has attracted significant attention. This review provides a comprehensive overview recent advances in catalyst design to improve C selectivity and operational stability. It begins with an analysis the fundamental reaction pathways for formation, encompassing both established emerging mechanisms, which offer critical insights design. In situ techniques, essential validating these by real‐time observation intermediates material evolution, are also introduced. A key focus this is placed on how enhance through manipulation, particularly emphasizing catalytic site construction promote C─C coupling via increasing * coverage optimizing protonation. Additionally, challenge maintaining activity under conditions discussed, highlighting reduction active charged Cu species materials reconstruction as major obstacles. To address these, describes strategies preserve sites control including novel utilization mitigation reconstruction. By presenting developments challenges ahead, aims guide future conversion.
