Abstract

Electropolymerized films of Co(III)tetra(4-hydroxyphenyl)porphyrin doped with ionic-liquid-functionalized graphene were obtained by a simple one-step preparation procedure. Spectroscopic (UV-Vis., Raman), microscopic (AFM, SEM), and electrochemical methods were used to characterize the films. The composite films show considerable lower H₂O₂ yields and at more positive potentials for O₂ reduction, as compared to the undoped ones. Stability during long-term use of films applied on electrodes, including porous ones, allow to consider them as possible non-noble catalyst based O₂ reduction cathodes in fuel cells.
