▎ 摘 要
A novel method was developed to synthesize reduced graphene oxide/alumina nanocomposite (RGO/Al2O3) by in situ depositing Al2O3 nanoparticles on graphene oxide flakes by a dry sol-gel process. The scanning electron microscopy and energy dispersive X-ray spectroscopy investigations results showed that Al2O3 nanoparticles (19 +/- 5nm) were homogeneously distributed onto the surface of curly-shaped RGO flakes acting as a spacer between individual flakes. The high BET-specific surface area of the analyzed composite (242.4m(2)/g) together with very low open porosity indicates that RGO/Al2O3 nanocomposites have a very friable structure and show low tendency to agglomeration.
