Abstract

Fe(III) tetra-(o-aminophenyl)porphyrin and Fe(III) tetra-(N-(2-hydroxyethyl)pyridyl)-porphyrin were attached to glassy carbon electrodes through amidization or esterifification of the methyl acryl chloride polymer. Long-term stability as well as high coverage (up to 10^-9 mol cm^-2) enabled these electrodes to be useful with respect to catalysis of oxygen reduction. The reduction of O₂ to H₂O₂ or H₂O can be controlled by changing the surface coverage of the porphyrin. Based on results obtained for dissolved, adsorbed and polymercoated porphyrin, a general mechanism, for O₂ electrocatalysis is proposed.
