Abstract

Electron beam assisted method has been employed for the synthesis of silver-reduced graphene oxide (Ag-rGO) nanocomposite in the presence of isopropyl alcohol and polyvinyl pyrrolidine. The decoration of face centered cubic silver nanoparticles (AgNPs) of size 8 nm on reduced graphene oxide has been confirmed by UV-visible spectroscopy, X-ray Diffractogram and Transmission electron microscopy. Raman spectra showed the increase in the disorder parameter (I_D/I_G) of Ag-rGO after electron irradiation due to the formation of large number of small sp² domains. Moreover, as an application of the synthesized Ag-rGO sample showed an enhanced photo-catalytic degradation of methylene blue compared to graphene oxide, rGO and AgNPs under sunlight.
