| Abstract: | The surface electrochemistry of a graphite electrode surface modified with cationic, tetra-(N-methyl)pyridiniumporphyrazinocopper is reported. The surface deposited species is spontaneously reduced by one electron by the electron rich graphite surface. Several concerted two-electron processes are recorded. A Pourbaix diagram is used to display the various species that can be identified on the surface with change of electrode polarization and pH of the electrolyte. |
