Adequately stabilized and exposed Cu/CuₓO heterojunction on porous carbon nanofibers

This article discusses a study on a new copper-based catalyst structure that significantly improves the efficiency of converting carbon dioxide into ethanol using electrochemical methods. Researchers stabilized copper oxides within carbon nanofibers, creating a Cu/CuₓO heterojunction. This structure showed exceptional performance in reducing CO₂ with high stability under varying electrical conditions, maintaining effectiveness even at high current densities. The findings, published by the Chinese Academy of Sciences, also highlight the benefits of using porous carbon nanofibers to enhance the exposure of active sites in the catalyst, leading to better performance and lower metal usage.
