Abstract
In this work a composite of Graphene Oxide (GO) supported α-Fe2O3 nanoparticles (GF) has been synthesized via a simple co-precipitation method. Structural, and morphological study of nanocomposite (GF) are examined by powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FESEM) and Transmission electron microscopy (TEM). The XRD study indicates that Graphene oxide is implanted with well crystalline α-Fe2O3 which has pure rhombohedral phase. Surface morphological study of SEM depicts sphere-like shaped α-Fe2O3 particles with formation of clusters have been embedded on Graphene oxide nano sheet. TEM image reveals that GO sheet acts as a good supporting material for anchoring nano sized α -Fe2O3 particles. Efficiency of dye removal of the prepared GF composite has been measured by the degradation of methylene blue (MB) in an aqueous solution under visible light irradiation. The degradation of the dye has been evaluated by a UV-visible spectroscopy, by decrease in the intensity of absorbance and concentration. The degradation efficiency of GF is found to be 90% towards MB.
