A Review of CO₂ Electroreduction to Ethanol: C–C Coupling Mechanistic Insights and Catalyst Design

Focusing on the economic viability of ethanol products and the application value of eCO₂RR, this research anchors its core from an industrial conversion perspective, combining academic depth with practical orientation. Systematically integrating multipath reaction mechanisms, advanced characterization techniques, and the active sites and performance metrics of various electrocatalysts, a comprehensive knowledge framework has been established. Proposing a rational design strategy for next-generation highly selective ethanol synthesis electrocatalysts, this work provides a clear research direction for this field.
