The formal potentials in cyclic voltammograms of these 3+ valence complexes are followed: Co〓-TPPS (-0.08V )＞Fe〓TPPS (-0.14V)＞Mn〓-TPPS (-0.23V). The electrochemical reaction of Mn〓-TPPS is reversible, and both of Co〓-TPPS and Fe〓-TPPS are quasi-reversible. The standard heterogeneous rate constants of Co〓-TPPS and Fe〓-TPPS were determined to be 1. 4×10〓cm/s and 1.4×10〓cm/s respectively. The rates of electrode reaction are as followed: Mn〓-TPPS＞Co〓-TPPS＞Fe〓-TPPS, e.i. Mn〓-TPPS is the most easily oxidized by the dissolved oxygen, and Fe〓-TPPS is oxidized slower than Co〓-TPPS. Ni〓-TPPS can not be oxidized. It is considered that oxygen plays an important role in the valence change of central metal atom and the rate of electron transfer in some metalloporphyrins.
