Abstract

An original copper-phenolate complex, mimicking the active center of galactose oxidase, featuring a pyrene group was synthesized. Supramolecular pi-stacking allows its efficient and soft immobilization at the surface of a Multi-Walled Carbon Nanotube (MWCNT) electrode. This MWCNT-supported galactose oxidase model exhibits a 4 H+/4 e− electrocatalytic activity towards oxygen reduction at a redox potential of 0.60 V vs. RHE at pH 5.
