Abstract

Six type-modified electrodes by electropolymerization of tetrakis(x-aminophenyl)porphyrins, where x = 2, 3 or 4, and their Cu(II) and Ni(II) complexes in HCl solution were prepared and characterized by cyclic voltammetry, atomic force microscopy and UV-VIS spectroscopy. The morphology of the polymers depends on the position of the amino groups. The modified electrodes show interesting electrocatalytic activity toward reduction of nitrites. The catalytic behavior strongly depends on the nature of the metal and the position of the amino groups. <p>
