Abstract

Graphene oxide (GO) was synthesized using Sri Lankan naturally available graphite and Fe3O4 nanoparticles were successfully incorporated fabricating magnetically separable GO/Fe3O4 nanocomposite. The synthesized nanocomposites were characterized by X-ray diffractometry (XRD), Scanning electron microscopy (SEM), and FT-IR spectroscopy. Crystalline phases of GO and Fe3O4 nanoparticles were identified by XRD patterns, while the presence of functional groups such as –COOH, OH, CH2 was confirmed by FT-IR spectroscopy. SEM images show that Fe3O4 nanoparticles with an average particle size of 107 nm ranging between 56-150 nm are dispersed on GO while restacking and folding of the nanosheets have been observed with incorporation of Fe3O4 nanoparticles. The photocatalytic performance of the photocatalysts was evaluated on photodegradation of methylene blue under visible light irradiation. The GO/Fe3O4 shows better adsorption behavior and excellent photocatalytic activity where it could be successfully used for three cycles without significant activity loss. This is due to the enhanced charge separation resulted due to the presence of GO sheets and better interactions between GO and Fe3O4.
