A facile hydrothermal route has been used to produce a SnO 2 (tin oxide)/RGO (reduced graphene oxide) nanocomposite. The microstructure and properties of the prepared nanocomposite were studied by an X-ray diffraction (XRD), fi eld emission scanning electron microscope (FE-SEM), Fourier transformed infrared (FTIR), UV–Vis analysis, and transmission electron microscope (TEM). The formation of SnO 2 phase over RGO is confirmed by the XRD and FTIR results. The absence of a distinct peak of GO in the SnO 2 /RGO nanocomposite produced hydrothermally shows the reduction of GO to RGO com- pletely. FE-SEM and TEM images show that SnO 2 nanoparticles with size about 20 nm distributed homogeneously on the graphene surface. UV–Vis analysis of the SnO 2 /RGO sample exhibits broad absorption in the visible range (400–700 nm) indicating the SnO 2 formation on the sheets of reduced graphene oxide. Moreover, the nanocomposite was employed as a photocatalyst under UV light irradiations to the removal of methylene blue (MB). The produced SnO 2 /RGO nanocomposite removes the absorption peak of MB at around 665 nm within 20 min, implying the nanocomposite possesses good photo- catalytic efficiency under UV light irradiations.
