Abstract

This work, reports on the results of research, fabrication of natural-based Graphene/SiO2 nanocomposites; graphene (GO) was prepared from coconut shells using the Hamers method and silica nanoparticles (SiO2) derived from Tetraethyl-orthosilicate precursors. Graphene/SiO2 nanocomposite fabrication using the one-pot process. The Crystal structure was analyzed using XRD, functional groups with FTIR and D-band and G-band that identified sp2 orbitals with Raman Spectroscopy. The analysis of adsorption properties of methylene blue dyes dissolved in water studied by UV-Vis spectroscopy. Graphene/SiO2 characteristics are obtained both in terms of structure and adsorption power of colours in the water, which is characterized by a trend of decreasing adsorption intensity on the UV-Vis curve.

Keywords: nanocomposite graphene graphene/sio2
