Abstract

The adsorption of iron(111)-tetra (N,N,N-trimethylanilinium) porphyrin on glassy carbon was studied in aqueous solutions using cyclic voltammetry, differential pulse voltammetry, chronoamperometry, and the RRDE technique. The porphyrin was found to catalyze oxygen electroreduction; the overpotential is reduced by about 400 mV and the hydrogen peroxide yield is ≃ 5% compared to ≃ 25% in the absence of catalyst.
