Abstract—Ternary Ag/Polyaniline/Au nanocomposites were synthesized successfully by immobilizing of Au
nanoparticles (NPs) on the surface of Ag/Polyaniline (PANI) nanocomposites. Ag/PANI nanocomposites were
prepared via in situ chemical polymerization of aniline in the presence of 4-aminothiophenol (4-ATP) capped
silver colloidal NPs. Then, uniform gold (Au) NPs were assembled on the surface of resulted Ag/PANI nano-
composites through electrostatic interaction to get Ag/Polyaniline/Au nanocomposites. The nanocomposites
were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray
diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), ultraviolet visible spectroscopy (UV–Vis),
thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). Moreover,
Ag/PANI/Au nanocomposites were immobilized on the surface of a glassy carbon electrode and showed
enhanced electrocatalytic activity for the reduction of H2O2 compared with Ag/PANI.
