Stoichiometric and electrocatalytic production of hydrogen peroxide driven by a water-soluble copper(ii) complex

Abstract

Herein, a water-soluble molecular copper complex was investigated as a catalyst for O₂ reduction in both water and an organic solvent. Although the quasi-stoichiometric oxygen reduction reaction (ORR) for the formation of H₂O₂ was conducted in an organic solvent and revealed mechanistic insights into the ORR, the electrocatalytic production of H₂O₂ was achieved in an aqueous medium.
