The inhibition behavior of 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine (T4PP) as an environmentbenign corrosion inhibitor for N80 steel was investigated in 3.5 wt.% NaCl solution by means of potentiodynamic polarization, AC impedance, and quantum chemical calculations. The results showed that 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine can inhibit the corrosion of N80 steel. The adsorption of T4PP on the N80 steel surface obeyed the Langmuir adsorption isotherm. The quantum chemical calculations were applied to elucidate adsorption pattern of inhibitor molecules on steel surface.
