Preparation and Characterization of Graphene Oxide from Rice Husk

Abstract

Preparation and characterization of Graphene Oxide (GO) Fe₃O₄ nanocomposite has been done. The characterized by XRD showed that graphite,GO and GO-Fe₃O₄ were amorph. Characterized by FTIR showed that there were a distinctive vibration bands of C-O,C=O, C=C, and OH, and additional bands belong to Fe-O dan Fe-C for the GO-Fe₃O₄. FESEM analysed showed that GO have smooths and sheets, and fill the wrinkled circle on the surface GO was showed presence of Fe₃O₄. The diameters of Fe₃O₄ was 39 nm. Atoms distribution Fe, C, and O of Fe₃O₄ on the GO sheets showed 15 %. D-band and G-band of GO were 1331 cm^-1 dan 1570 cm^-1 and D-band of GO-Fe₃O₄ were 1331 cm^-1 based on analyzed using Raman spectroscopy.
