Three series of cobalt(III) corroles were tested as catalysts for the electroreduction of dioxygen to water. One was a simple monocorrole represented as (Me(4)Ph(5)Cor)Co, one a face-to-face biscorrole linked by an anthracene (A), biphenylene (B), 9,

The electro-oxidation of cobalt (II) octaethylporphyrin adsorbed on graphite electrodes, Co^(II)(OEP)_(ads') to Co^(III)(OEP) ^+_(ads), in the presence of aqueous solutions of CO leads to catalytic oxidation of CO to CO_2. No such oxidation occurs wi

Rates of electron-transfer between redox reactants located on opposite sides of the interface between thin layers of organic solvents on graphite electrode and aqueous solutions were measured by means of steady-state electrochemistry. Changes in the

A set of cobalt porphyrins containing alkyl substituents in their meso sites were synthesized and compared as catalysts for the electroreduction of O2 when adsorbed on the surface of graphite electrodes. The meso substituents examined included ethyl,

The electroreduction of O 2 in two aprotic solvents (nitrobenzene and acetonitrile) was examined in the absence and in the presence of the very strong Lewis acid, triphenylmethyl cation, φ 3 C + (φ=phenyl). The addition of φ 3 C + causes the elect

Four cobalt porphyrins were adsorbed on graphite electrodes and used to catalyze the electroreduction of O2. The two porphyrins without substituent groups in the meso positions of the porphyrin ring operated at the most positive potentials and cataly

Unlike most simple, monomeric cobalt porphyrins, the cobalt tetramethylporphyrin identified in the title catalyzes the electroreduction of O2 to H2O instead of H2O2. On graphite electrodes, coatings of the porphyrin prepared by irreversible adsorptio
