▎ 摘　　要

We report a simple and effective route to synthesize graphene based platinium selenide nanocomposites by facile and fast microwave assisted techniques. The "as-prepared" composites are further characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), Raman spectroscopic analysis, UV-vis absorbance spectra analysis and UV-vis diffuse reflectance spectra (DRS). The photocatalytic activities were investigated by the degradation of methylene blue and rhudamine B as standard dye. This result gives a promising development towards graphene based efficient photocatalyst that employed visible light as an energy source. (C) 2013 Elsevier Ltd. All rights reserved.
