Synthesis and characterization of graphene oxide by modified hummer method

Abstract

Graphene oxide was prepared by oxidizing the graphite powder using the modified hummer method. Characterization studies are done to investigate physical and chemical properties. In this study, Scanning electron microscopy(SEM), Energy dispersive x-ray spectroscopy(EDX), Fourier transform infrared spectroscopy (FTIR), and X-Ray Diffraction(XRD) results are used.FTIR shows that graphite oxidized and formed oxygen atoms in the graphite layer and forms C=O,C-H,COOH Chemical bonding with graphene. The XRD results showed 2 of 11.300 with interlayer spacing of 0.771nmSEM images report ultra-thin layers. It is a promising method to synthesize GO for various applications like biomedical, electrical, and others.
