Abstract
Electrocatalytic water oxidation using the oxidatively robust 2,7-[bis(2-pyridylmethyl)aminomethyl]-1,8-naphthyridine ligand (BPMAN)-based dinuclear copper(II) complex, [Cu2(BPMAN)(μ-OH)]3+, has been investigated. This catalyst exhibits high reactivity and stability towards water oxidation in neutral aqueous solutions. DFT calculations suggest that the OO bond formation takes place by an intramolecular direct coupling mechanism rather than by a nucleophilic attack of water on the high-oxidation-state CuIVO moiety.
CuIII not CuIV: A robust dinuclear CuII complex catalyzed water oxidation in a neutral aqueous solution. The OO bond formation was proceeded by an intramolecular interaction between two CuIII centers rather than by the high-oxidation-state CuIVO moiety as previously reported.
