Graphene oxide (GO) is an electrical insulator as most of the carbon atoms in this material are sp~3-hybridized. Its physical, optical and chemical properties depend on the type and degree of reduction process. Presently, copper ion irradiation of GO foil has been performed at Ion Beam ...
Chemical exfoliation is proposed to produce graphene oxide, using sulfur-free expanded graphite. X-ray diffraction was employed to evaluate the structural properties of expanded graphite, expanded graphite oxide, and graphene oxide. The FITR spectroscopy was used to demonstrate infrared spectroscopy charact...
Nano Technology Metal Oxide Semiconductors (NTMOs) have been under a considerable attention. Nanocomposites of graphene with spinel chromites have applications in tuning bandgap, photocatalysis, dye-sorption, etc [20]. Material science's another powerful idea is the decoration of graphene oxide with ...
The graphite oxide was prepared by the modified Hummers method.The colloidal suspension of graphene oxide was obtained via ultrasonicating the graphite oxide in deionized water.Then graphene was prepared via the reduction of hydrazine hydrate.The reduced material was characterized by SEM,XRD and Raman...
Graphene oxide (GO) was synthesized using the modified Hummers method and characterized by XRD and FTIR. The sorption of 60 Co(II) on GO as a function of contact time, pH, polyacrylic acid, ionic strength, temperature and solution concentration was studied by batch technique. The sorption kine...

It is useful not only to characterize nanoscale electronic proper- ties but also to investigate atomic-scale friction properties, reduction of graphene oxide (GO), oxidation and hydrogena- tion of pristine graphene, etc. Depending on the fabrication method and the type of substrate used, the ...
2. Graphene Nanocomposites The final functional andstructural propertiesof graphene nanocomposites depend on several factors, including graphene quality, matrix characteristics, and nanocomposite processing methods. The synthesis conditions for synthesizing pristine graphene,graphene oxide(GO), and graphene composi...
Graphene oxide (GO) nanosheets impregnated with silver nanoparticles (Ag NPs) were fabricated by the in situ reduction of adsorbed Ag+ by hydroquinone (HQ) in a citrate buffer solution. Paper-like Ag NP/GO composite materials were fabricated owing to convenient structure characterization and antibact...
