▎ 摘　　要

A new process to decorate graphene oxide (GO) with silver nanoparticles was developed through electroless deposition technique, which was performed by treating GO with Sn2+ 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 mu M to 20 mu M with a detection limit of 0.5 mu M.
