Tuning C–C Coupling and Selectivity in CO2 Electrochemical Reduction Reaction via Pyramidal Dilute Sn–Cu Alloy

The electrochemical conversion of carbon dioxide (CO₂) into value-added fuels is emerging as a promising strategy to combat climate change and support carbon neutrality. Despite recent advances, the selective generation of higher-order hydrocarbons (C₂₊ products) remains a significant challenge due to kinetic and thermodynamic limitations. In this study, we report the synthesis of electrocatalysts comprised of a pyramidal dilute Sn-Cu alloy, …
