Abstract

Oxide-derived (OD) Sn-Pb-Sb, and Cu-Sn alloy catalysts were prepared for electrochemical reduction of CO₂ (eCO₂R) for formate (HCOO^-) and carbon monoxide (CO) production. The morphology, elemental mapping, and electrochemical behavior of the electrocatalysts were probed systematically. The results demonstrate that OD-Sn-Pb-Sb alloy improved the FEHCCO-remarkably from 68% to 91% without any reduction in current density. For eCO₂R to CO production, Cu-Sn alloy electrodes were prepared and the results show that Cu-Sn alloy electrode reduces C0₂ to CO selectively (FE∼91%) at a high current density. The improved eCO₂R performance of OD-Sn-Pb-Sb and Cu-Sn electrodes relative to their pristine electrodes could be attributed to local geometric and electronic structural changes.
