sp2 carbon nanostructures(carbon nanotube, graphene, and graphene oxide) has received of attention due to their unique physical and chemical properties. Especially, graphene and graphene oxide are a two-dimensional material with a single atomic layer of carbon atoms arranged in a hexagonal lattice. Due to their unique structure, exhibits unusual optical and electronic properties. Graphene sheets offer extraordinary electronic, thermal, and mechanical properties and are expected to find a variety of applications, such as sensors, nanocomposites, batteries, supercapacitors, and hydrogen storage. In this study, we composed silver decorated graphene oxide by thiol groups on graphene oxide surfaces. We have characterized of Ag/graphene oxide composites was performed with transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman and X-ray photoelectron spectroscopy (XPS). Electrochemical characteristic of hydrazine oxidation is also investigated via cyclic voltammetry (CV) measurement. |
