Iodide-derived nanostructured silver promotes selective and efficient carbon dioxide conversion into carbon monoxide

Abstract

It is of great importance to design and develop highly active and selective electrocatalysts for the CO2 reduction reaction (CO2RR). In this communication, we report an iodide-derived nanostructured silver catalyst (ID-Ag) as an excellent CO2RR catalyst that is able to electrochemically reduce CO2 to CO with approximately 94.5% selectivity at the potential of −0.7 V in CO2-saturated 0.5 M KHCO3. This suggests that the highly electrochemical active surface area and adsorbed I anions onto the surfaces of the electrode contribute to the enhanced activity and selectivity of the nanostructured Ag electrocatalyst toward CO2 reduction.
