Laccase Mimics: Probing the Electrocatalytic Potential for CO Reduction.

The intricate copper-based redox center in laccase serves as an exemplar for developing laccase mimics. The current need of the hour is exploring the application of these biogenic laccase mimics beyond their traditional roles in sustainable energy conversion. This study investigates the untapped potential of laccase and their biogenic copper-amino acid mimic in the context of electrochemical CO₂ reduction (ECR), leveraging the Cu/Cu redox system.
