Synthesis of Graphene Oxide Via Microwave Assisted Eco-Friendly Method Versus Modified Hummer Method

Abstract

Using eco-friendly chemicals, a unique method for synthesizing graphene oxide (GO) by microwave radiation along with organic solvents is described. Microwave radiation was utilized to cause the graphite worm to expand significantly in all directions.SEM images were used to assess the morphology and structure of GO nanomaterials. X-ray diffraction, UV-Vis, and Fourier-transform infrared spectroscopies were used to identify the oxygenated groups on the GO surface. When compared to the conventional Hummer’s technique, the new microwave-assisted approach significantly reduces reaction time and is much more eco-sustainable. Aside from being environmentally sustainable, the suggested approach has the appealing feature of producing a large number of graphene nano-sheets quickly. This article compares efficient and environmentally microwave-assisted and conventional modified hummer methods for graphene oxide preparation..

“…The MG P shows a sharp 2 θ peak at 26.52° corresponding to an interplanar distance of .35 nm, as depicted in Figure 8. The peak for GO appeared at 2 θ 10.29° in Figure 8 shows that the interplanar spacing has been increased, that is, .85 nm, indicating that the oxygenating functional group was introduced on the surface of graphite sheets 27,36 …”

“…Preparation of graphene oxide from MG P GO was synthesized by using Hummers method, which resulted in surface-functionalized graphite powder. 26,27 As depicted in Figure 1, the final suspension of GO was yellowish brown in color. Afterwards, the functionalized graphite powder, GO, was dispersed in an aqueous media using ultrasonication.…”
