Abstract:
Reduced graphene oxide/alumina (rGO/Al2O3) nanocomposite powdershave been prepared successfully via mixing of synthesized graphene oxide(GO) and aluminum nitrate using a two-step process: synthesis of GO/Al2O3composite through ultrasonication treatment and chemically reduction of thesynthesized composite via refluxing in presence of hydrazine hydrate. Thethickness of synthesized GO sheets and morphology of the preparedcomposite were characterized using atomic force microscopy (AFM) andscanning electron microscopy (SEM), respectively. According to the AFManalysis, the synthesized GO can be considered as a monolayer. TheFourier transform-infrared (FT-IR) spectrum index bands of prepared GOand rGO/Al2O3 were appeared at about 1725 and 1160 cm-1, respectively.
