Abstract

Core–shell nanowires with conductive metal cores and active catalyst shells hold great promise for making a catalyst electrode with high total activity. Indeed, core–shell nanowire arrays have been demonstrated as the catalyst in various electrochemical reactions, yet their catalytic roles are underexplored for carbon dioxide (CO2) electroreduction. Herein, we report a reduced silver@silver chloride (Ag@AgClx) core–shell nanowire array for electrocatalytic CO2 reduction. The Ag@AgClx core–shell array electrode shows high total activity including low onset potential and high current density. The strong electronic coupling between AgClx and the Ag core results in the record-high specific CO2RR activity to date.
