A new process to decorate graphene oxide (GO) with silver nanoparticles was developed through electroless deposition technique, which was performed by treating GO with Sn 2+ first and then with Ag + . Silver nanoparticles‐GO (AgNPs‐GO) nanocomposites were prepared by this technique. The process was monitored using UV‐vis spectroscopy, Raman spectroscopy and transmission electron microscopy (TEM). The electrochemical behaviour of AgNPs‐GO modified glassy carbon electrode was investigated by cyclic voltammetry. The potential application of this technique for hydrogen peroxide detection was tested with a range from 10 µM to 20 mM with a detection limit of 0.5 µM.
