| Abstract: | The electrocatalytic reduction of dioxygen on the gas diffusion electrode of nafion modified by macrocyclic complexes of cobalt were studied systematically by stable polarization curves. The effects of electrostatic interaction between the complex coating and Nafion film on electrocatalytic reduction of dioxygen in the presence of Co(TMAP) and CoTSPc catalysts are discussed. |
