SYNTHESIS AND CHARACTERIZATION OF GRAPHENEOXIDE FROM HYPHAENETHEBAICA (DOUMPALM) SHELL

Abstract

Graphene oxide (GO) is a significant carbon component of two dimensional nanomaterial with unique features and wide range of application owing to its physical, chemical and electronic properties. The primary aim of this work is synthesis and characterization of graphene oxide. The graphene oxide was prepared by Hummer’s method using grapheme synthesized from Hyphaenethebaica shell (Doumpalm shell) as carbon based material. The characterization of GO was carried out using X-ray Diffraction Analysis(XRD),Fourier Transform Infrared (FTIR), Thermogravimetric analysis (TGA),Scanning Electron Microscopy (SEM) and Brunauer Emmett Teller (BET). The XRD images howed the formation of grapheme oxide from a strong peak at angle19.6o revealing its crystalline structure and indicates that the chemical reaction had an important role in the formation of the GO particle. This was confirmed by the FTIR, where the presence of various oxygen functional groups were widentified. The FTIR band showed that the GO had some functional oxygen group within its structure. The SEM image showed the morphological structure of GO with rough surface, while the BET data result proved that the graphene oxide has a large surface area
(356.276 m2 /g), pore volume (2.15 m3/g) and poresize (2.138 mm).
