In this study, the synthesis and characterization of a novel Graphene/Si nanomaterial composite was investigated successfully by Sonication method. The coupling of silica to GO and the partial reduction of GO were demonstrated and confirmed by characterization techniques such as IR, Raman, XRD and SEM. Powder X-ray diffraction shows that G/Ag nanocomposite is polycrystalline in nature. The Raman spectra of the composites show a diminished intensity ratio of D to G band indicating that GO was reduced to graphene sheets. The formation of nanoparticles is indicated by the SPR peak of Si NPs at around 374 nm in the rGO/Si NCs. XRD & Raman analysis gives the evidence regarding the formulation of rGO/Si NCs. SEM indicates that Si on graphene sheet are lamellar fold nanostructure in the range 20-27 nm. Moreover, SEM images showed that the occurred Si nanoparticles were well dispersed & attached to the graphene sheet. These composites may find applications in the development of sensor, supercapacitor device, or as support for catalysts, and others.
