Özet
A poly (p-aminophenol) film (PPAP) and bimetallic nanoparticles modified polymer film galssy carbon electrodes (GCE), Au-Pt/PPAP/GCE, Au-Ag/PPAP/GCE and Au-Cu/PPAP/GCE were prepared by electrochemical techniques. The modified electrode surfaces were characterized using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The electrocatalytic activities of modified PPAP/GC and bulk electrodes were investigated for borohydride oxidation in alkaline media and the response of electrodes were compared with each other from the corresponding voltammetric curves. There was no any oxidation take place on bare GCE, PPAP/GCE and Cu/PPAP/GCE in the presence of sodium borohydride. Au-Pt bimetallic modified PPAP/GGCE showed higher catalytic activity toward sodium borohydride in terms of the manner of both peak potential and peak current.
