Modified hummers method synthesis and structural characterisation of graphene oxide
摘要：
Graphene oxide (GO) was synthesised using modified hummers method. X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy (RM) and Atomic Force Microscopy (AFM) were utilised to acquire the structural properties of GO. Each spectroscopic technique reveals unique features about the surface morphology of graphene oxide. XRD confirmed the crystalline nanosheets stacking of a carbon honeycomb. SEM and TEM revealed wrinkles and folding of planar honeycomb layers. FTIR and RM indicated the presence of carbonyl, alkoxy, epoxy, and hydroxyl functional groups. AFM further confirmed the surface roughness and the thickness of the GO nanosheets.
