  Abstract:  The electrochemical characterization of 5,10,15,20-tetrakis(4-pyridyl)-21H,23H-porphine (TPyP) and of Zn(II)5,10,15,20-tetrapyridylporphyrin (ZnPyP) is presented. Voltammetric and corrosion studies were carried out in order to investigate the electroactivity of TPYP and ZnPyP. Cyclic voltammograms obtained on Pt electrode, in H2SO4 0.1N or a mixture (1:1 vol.) of H2SO4 0.1N and AcCN, present two peaks for oxidation and one for reduction in case of TPyP and two oxidation and two reduction peaks for ZnPyP. The corrosion inhibiting abilities of TPyP and ZnPyP were illustrated by potentiodynamic curves obtained on carbon steel in 1N H2SO4, indicating a decrease of the current in the active region of the anodic polarization curves. Corrosion tests monitoring the mass loss of steel were also carried out.
