Photocatalytic properties under visible light with graphene based platinium selenide nanocomposites synthesized by microwave assisted method

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.
