摘要：
The electropolymerization. of polyaniline (PAn) film in the presence of planar binuclear cobalt phthalocyanine (bi-CoPc) on different concentration of ethanol on glassy carbon electrode was examined by cyclic voltammetry (CV). The effects of ethanol on properties of films on indium-tin oxide (ITO) glass were investigated by CV, ultraviole-visible spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscope. The results show that in the presence of (10%) ethanol which the electropolymerization. rate was enhanced, and the doping amount of bi-CoPc was increased, leads to finer structure of PAn film. It is found that the electrocatalytic activity of bi-CoPc-PAn modified electrodes towards oxygen reduction is higher in the presence of 10% ethanol than that of its absence.
