Abstract
Systems and methods for the electrochemical reduction of carbon dioxide are disclosed. The systems involve an electrochemical cell having a cathode of anodized silver and the methods involve introducing carbon dioxide into such a system and applying a potential. The disclosed systems and methods have improved carbon monoxide production selectivity, support higher current density, and have improved efficiency in comparison to existing silver-based CO2 electroreduction devices.
