▎ 摘　　要

A facile and straightforward method has been developed to synthesize silver nanoparticles decorated on reduced graphene oxide (RGO) nanosheets through hydrothermal reaction. The composite was characterized by XRD, UV-Visible spectroscopy, SEM and TEM techniques. In this synthesized RGO-Ag nanocomposite, the Ag nanoparticles size ranges 30-50 nm. Moreover, the RGO-Ag composites exhibited excellent photocatalytic activity towards the degradation of methylene blue (MB) in presence of sunlight. This photocatalytic reaction is completed within 20 min and the rate of reaction depends on the amount of RGO present in the nanocomposites.
