Electrocatalytic water oxidation by copper(ii) complexes containing a tetra- or pentadentate amine-pyridine ligand†
Abstract
Two water soluble copper(II) complexes containing amine-pyridine ligands were found to be catalytically active for water oxidation reactions in basic solutions, with observed rate constants of 13.1ā18.7 sā1. These complexes are robust in basic solutions and displayed good stability over 5 h of electrolysis in pH 11.5 phosphate buffer at 1.4 V vs. NHE.
