CuIr Nanoparticles for Electrochemical Reduction of CO₂ to t‐BuOH (Adv. Energy Mater. 22/2023)

Carbon Dioxide Reduction In article number 2300749, Woong Kim and co-workers demonstrate that CuxIr1−x alloy nanoparticles can electrochemically convert CO2 into t-BuOH with a Faradaic efficiency of 14.8%. The study suggests that the strong electronic interaction between Cu and Ir along with the high oxophilicity of the Ir-rich surface can effectively stabilize oxygen-bound intermediates, thereby promoting a productive pathway for multi-carbon production.
