A simple approach of synthesis of graphene oxide from pure graphite: Time stirring duration variation

Abstract

In this work, the process of synthesis of graphene oxide was carried using modified Hummer's method. Synthesizing graphene oxide was obtained by threating pure graphite using KMnO4 and H2SO4 as the oxidizing agent and sonicating the solution to separate the layers of the graphite. The result of the graphene oxide then reduced to reduce graphene oxide using Aluminum powder (Al). The process of synthesizing graphene oxide was controlled by reaction/stirring time duration at constant temperature 40 °C. Graphite oxide, graphene oxide and reduce graphene oxide were characterize using Scanning Electron Microscope, UV-Visible spectra, X-ray Diffraction, and FT-IR spectroscopy analysis. The result shows that the 7 hours reaction/stirring time duration has better degree of oxidation. The simple approach is designed to produce large scale production of graphene oxide and reduce graphene oxide.
