Özet
An Au-Ag nanoparticles modified poly(p-aminophenol) film electrode (Au-Ag/PPAP/GCE) was prepared by cyclic voltammetry. The electrochemical behaviour of ammonia borane (NH3BH3, AB) was studied in alkaline media at Au-Ag/PPAP/GCE. The surface morphology and chemistry were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and CV techniques. There was no any oxidation reaction occurs on bare GCE and PPAP/GCE in the presence of AB. Among the five electrodes which were Au disk, Ag/PPAP/GCE, Au/PPAP/GCE and Au-Ag/PAP/GCE. The comparative studies were revealed that Au-Ag/PPAP/GCE yield the best results due to the highest peak current and shifting the oxidation potential to more negative values for AB oxidation.
