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.
