Modified hummers's method
Abstract:
Graphene was synthesized through chemical cleavage followed by reduction process and through liquid-phase exfoliation methods. The characteristics of synthesized graphene were investigated by Raman spectroscopy, FTIR, SEM, XRD and UV-Visible spectrophotometry. It was found that Graphene Oxide (GO) synthesized by modified Hummers method had carboxylic acid, hydroxyl, and ether groups confirming that graphite was successfully oxidized. The result also showed that graphene oxide consisted of 12 layers and the layer distance was in the range of 0.670.72 nm. In liquid-phase exfoliation method, graphene sheets were synthesized by mixing graphite with naphthalene and N-methyl-2-pyrrolidone (NMP) followed by sonication. The results indicated that the inter layer spacing of graphite was expanded from 0.3356 to 0.3364 nm. The highest graphene concentration was up to 3.26 mg/mL and the yield was 54.34%.
