Abstract

The electrochemical reductions and oxidations of tetraphenylporphyrin (TPP) and vanadyl porphyrin (TPP-VO) were investigated in dimethylformamide at platinum, glass carbon and microdisk electrodes. A new electrode reaction mechanism of TPP and TPP-VO is proposed. The kinetic parameters have also been determined. In addition, the theory of molecular hybrid orbitals is used to explain the reduction and oxidation regularity of the transition metal porphyrins.
