Modification of hummers presses for synthesis graphene oxide nano-sheets and graphene oxide /Ag nanocomposites

Abstract

Graphite is a based on three-domination functionalized carbon content made up of millions of graphene layers. In this study, graphene oxide (GO) and graphene oxide\Ag nanocomposites (GO-Ag) have been synthesized in a single layer using a modified Hummer method. The morphology and structural characteristics of GO and GO-Ag nanocomposites were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmitted electron microscopy (TEM), and Raman spectroscopy. The results of TEM indicated the single and double layer structure with thickness of 4-6 nm for GO Nano-sheets prepared in this analysis. The particles size of silver on a surface of GO was to be less than 20 nm.
