title: Electrocatalytic activity of silver nanoparticles modified glassy carbon electrode as amperometric sensor for hydrogen peroxide.
abstract: A simple chemical route has been applied for the preparation of quasi-spherical silver (Ag) nanoparticles (NPs) with average diameter of 265 and 8 nm. The as prepared products were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-vis absorption spectroscopy. Ag NPs immobilized on glassy carbon (GC) electrode showed a superior electrocatalytic activity for the reduction of hydrogen peroxide (H2O2) in aqueous medium. The fabricated electrode was also applied for the amperometric detection of H2O2 and showed a favorable response at an applied potential of -0.5 V (vs. Ag/AgCl). The results demonstrate that the fabricated electrode has potential application for hydrogen peroxide sensor.
