Entrapment of a pyridine derivative within a copper-palladium alloy: A bifunctional catalyst for electrochemical reduction of CO₂ to alcohols with excellent selectivity and reusability

A novel bifunctional catalyst, [PYD]@Cu-Pd composite, was synthesized for the first time and used as a cathode for electrochemical reduction of CO₂. Methanol with 26% and ethanol with 12% Faradaic efficiency were obtained at the same [PYD]@Cu-Pd cathode using different potentials. Under both conditions, the [PYD]@Cu-Pd cathode shows remarkable stability and reusability.
