GO-Fe3O4 Nanocomposite from coconut shell: Synthesis and characterization

[摘要] Synthesis and characterization of graphene oxide nanocomposite from coconut shell GO-Fe3O4 has been done. Graphene oxide can be prepared using Hummer's method and Subsequently, the synthesis of GO-Fe3O4 nanocomposite was carried out by ultrasound assisted co-precipitation of iron (II) and (III) chlorides in the presence of GO. The formation of GO and graphene-Fe3O4 nanocomposite was confirmed by X-ray diffraction (XRD), Fourier transform-infrared (FTIR), SEM and Raman spectroscopy. The characteristics of GO-Fe3O4 as a result of synthesis from coconut shell analyzed using XRD showed that GO characteristics peak in accordance with the characteristics of GO-Fe3O4 in (JCPDS No. 88-0315). Analysis using FTIR was seen in 3421 cm-1 (O-H stretching), 1631 cm-1 (C = C aromatic), and 565 cm-1 (Fe-O). Analysis using SEM seen in the presence of Fe, O and C in the EDX analysis confirmed the formation of GO-Fe3O4 nanocomposite. Analysis using Raman spectroscopy showed that peaks of Fe3O4 were at wavelengths of 396 cm-1 because sp3 carbon was bound to Fe3O4 so that the peak band D was not present in GO-Fe3O4 spectroscopy.
