Abstract
Cobalt tetra-2,3-pyridineporphyrazine (CoPPA) is adsorbed irreversibly from its solution in sulfuric acid on the surface of pyrolytic graphi te upon cycling the electrode potential from -0.5 to 0.5 V. Voltammogr ams of electrosorbed CoPPA are characterized by two reversible redox p rocesses, whose potentials coincide with those of the redox processes of CoPPA dispersed on the surface of acetylene black. A technique of e lectrochemical preparation of composite CoPPA/polyaniline films is dev eloped, and the features of electrochemical and electrocatalytic behav ior of CoPPA in them are investigated.
