Tetrasulfonated iron phthalocyanines ( FePcS ) can be incorporated into electronically conducting polypyrrole by electrochemical polymerization of pyrrole in the presence of FePcS . The FePcS modified glassy carbon electrodes catalyzed the reduction of O 2 at potentials 250 to 800 mV less negative than at bare glassy carbon or at polypyrrole‐coated glassy carbon not containing FePcS . Rotating ring‐disk experiments indicated some hydrogen peroxide formation at most pH's. However, at high pH essentially exclusive reduction of O 2 to H 2 O was observed at potentials 250 mV less negative than at a non‐catalyzed electrode.
