Nanostructured Metallic Electrocatalysts for Carbon Dioxide Reduction

Abstract The recent development of nanostructured electrocatalysts for CO 2 reduction has attracted much attention because they exhibit unique properties compared to their bulk counterparts. In this minireview, the latest studies on electrocatalytic CO 2 reduction with a focus on the advances of nanostructured metallic electrocatalysts are reviewed and discussed. The distinct catalytic properties and potential challenges of nanostructured electrocatalysts are summarized. The behavior of nanosized catalysts in ionic liquid electrolytes is also discussed. Ideas for the design of next‐generation electrocatalysts by taking the advantages of nanostructured materials are proposed.
