Electrocatalytic Carbon Dioxide Reduction to Ethylene over Copper‐based Catalytic Systems

The electrocatalytic carbon dioxide (CO₂ ) conversion to ethylene (C₂ H₄ ) has attracted significant attention in recent years. Copper-based catalytic systems have been proven to be the most efficient for producing C₂ H₄ from electrocatalytic CO₂ reduction reaction. In this review, we present the recent progress on the electrocatalytic CO₂ reduction to C₂ H₄ over copper-based catalytic systems, mainly focusing on reaction mechanism, design of catalysts and influences of electrolyte, CO₂ supplement and electrolyzer on activity, selectivity and stability.
