Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

open access: yesAdvanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.
