Synthesize and Characterization of modified ordered mesoporous silica with graphene oxide

In this study, SBA-I 5 type ordered mesoporous silicas with high surface areas and mesopore volumes have been obtained using Pluronic P123 as Surfactant and tetraethyl orthosilicate (TEOS) during the synthesis process. Moreover, the surfactant removal process has been optimized to enhance the textural properties of the resulting materials. Therefore, silica-based ordered mesoporous materials exhibiting surface areas more than twice larger than those of conventional SBA-15 are reported. The properties of SBA-15 and modified nanocomposite were characterized by transmission electron microscope TEM, scanning electron microscope SEM, elemental analysis map, energy-dispersive X-ray spectroscopy EDS, thermogravimetric analysis TGA, elemental analysis CHNS, and Brunauer-Emmett-TellerBET techniques
