Upgrading carbon dioxide (CO2) to high-value multi-carbon (C2+) products is one promising avenue for fuel and chemical production. Among all monometallic catalysts, copper (Cu) has attracted much attention because of its unique ability to convert CO2 or CO2 derived carbon monoxide (CO) to C2+ products with an appreciable selectivity. While numerous attempts have been made to synthesize Cu nanostructures to expose desired facets, it remains a challenge to obtain high-quality nanostructured Cu catalysts for electroreduction of CO2/CO. Here, we report a system that has an acetate Faradaic efficiency of 48% with an acetate partial current density up to 131 mA cm-2 in electrochemical CO reduction, representing among the highest acetate selectivity that has been achieved in CO2/CO reduction.
