Abstract

A serious of nitrogen-doped reduced graphene oxide/barium tungstate (NRGO/BaWO₄) nanocomposites has been synthesized by microwave method and it was examined by the photocatalytic studies for the degradation of methylene blue (MB) dye under visible light irradiation. The as-synthesized catalysts were confirmed by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Photoluminescence Spectroscopy (PL) and Diffuse Reflectance Spectroscopy (DRS) techniques. The prepared nanocomposites are tested for its performance to the photodegradation of MB dye via illumination of 120 minutes under visible light source. Significantly, the 2.5%-NRGO-BaWO₄ nanocomposite indicated that the highest photocatalytic activity under visible light source. The observed photocatalytic performances were ascribed to the synergetic effects of NRGO and BaWO₄ and improved photogenerated electron-hole pairs charge separation efficiency. On the basis of the experimental results, we concluded that the new strategy of these types of photocatalytic property of NRGO/BaWO₄ based binary nanocomposites materials can be a suitable candidate for the various environmental applications.
