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 O2 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 pHs. However at high pH essentially exclusive non-catalyzed electrode. Author
