Özet
A highly active electrocatalyst has been developed based on poly(p-aminophenol) polymer film modified with Pt-Au bimetallic particles on a glassy carbon electrode (Pt-Au/PPAP/GCE) for electrocatalytic reduction of oxygen. The surface morphology and chemical analyses of the modified electrodes have been revealed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), and electrochemical impedance spectroscopy (EIS). The Pt-Au/PPAP/GCE has shown the best electrocatalytic activity towards O-2 reduction in comparison to the other used electrodes. The rotating disk electrode (RDE) studies have indicated that the oxygen reduction reaction takes place via almost four electrons on the Pt-Au/PPAP/GCE.
