Abstract

An interesting method for preparing a composite nanomaterial consisting of silica (SiO2) decorated onto the surface of graphene nanosheets is presented. Graphene/silica nanocomposite was prepared by the hydrolysis of tetraethyl orthosilicate (TEOS) in the presence of Graphene oxide (GO) obtained by a modified Hummer's method. The structure, morphology, pore diameter, pore volume, and surface area of the graphene/ SiO2 nano composite were obtained via XRD, Raman spectroscopy, SEM, TEM, BET and BJH method. The BET analysis suggested that the silica decorated graphene have the higher surface area than bare silica and graphene. The XRD spectra indicated the coexistence of silica and graphene in the composite particles. The morphological analysis suggested that the presence of SiO2 nanoparticles with similar sizes attached on the surface of graphene successfully. Due to its high surface area, high porosity, and other fascinating properties, it is an interesting material for in diverse energy applications such as solar cell, lithium-ion battery, electronic devices and supercapacitors
