SPECTROELECTROCHEMICAL STUDIES ON ITO MODIFIED ELECTRODES WITH A CONDUCTING COBALT (II) MACROCYCLE FILM IN THE ELECTROCHEMICAL REDUCTION OF CO2

The spectroelectrochemical properties of a conducting polymer derived from Co(II) tetra-3-amino-phenyl-porphyrin,(poly-Co(II)-TAPP) were studied towards the electrochemical reduction of CO2 on ITO surface. Under inert atmosphere, the results show that the polymer present a stable Co(I) oxidation sta...
