OXYGEN ELECTRODE ON THE BASIS OF SOME PORPHYRINES AND THEIR DERIVATIVE

Abstract

The oxidation-reduction behavior of 5,10,15,20-tetraphenylporphyrin, 5,10,15,20-tetra-(4-methoxyphenyl)-porphyrin, 5,10,15,20-tetra-(3,5-di-tretbutylphenyl)-porphyrin, 10,15,20-triphenyl-1-оxonaphtо-[2,3,4-c,d]-porphyrin, 5,10,15,20-tetra(penta‑fluorinephenyl)-porphyrin and them complexes with Co (II), Mn (III), Fe (III) forming part of oxygen gas-diffusion electrode in alkaline solution has been studied with cyclic voltammometry. Power resources of electrodes under cyclic loading have been researched. Сatalyst activity series dependingon the central atom and substitutes in ring.
