Chemical Design of Metal Complexes for Electrochemical Water Oxidation under Acidic Conditions

Abstract

The development of viable, stable, and highly efficient molecular water oxidation catalysts under acidic aqueous conditions is challenging with earth-abundant metals in the field of renewable energy based on their low stability and catalytic activity. Herein, we discussed the effectiveness of transition metal complexes for electrocatalytic water oxidation under acidic conditions. We identified the scientific challenges that should be overcome for the future development and application of water oxidation electrochemical catalysts.
