Oxygen reduction catalyzed by a water-soluble binuclear copper(ii) complex from a neutral aqueous solution

Chem Commun (Camb). 2017 Mar 14;53(22):3189-3192. doi: 10.1039/c6cc09206c.

Abstract

A water-soluble binuclear CuII complex, synthesized using a polypyridine-polyamide ligand, was able to catalyze oxygen reduction to water from neutral aqueous solutions. Electrocatalytic results suggested that one CuII center was first reduced by one electron to form a CuIICuI species, which reacted with O2 to give a superoxide radical intermediate.
