Synthesis of Graphene Oxide by Modified Hummers Method-An Overview

Abstract

Graphene is often hailed as a "wonder material" due to its remarkable properties and wide-ranging applications. Graphene oxide (GO) is interesting because its oxygen-containing functional groups make it highly dispersible in water and various solvents, allowing for easy processing and versatile applications. The modified Hummers' method for synthesizing GO enhances safety, efficiency, and material quality. Improved oxidation efficiency increases GO's oxygen content, enhancing hydrophilicity and dispersibility in water and solvents. The characterization of synthesized GO includes the use of several techniques to analyse its structure, composition, and properties, such as FTIR, XRD, FESEM, TEM, EDS, Raman, and UV-Visible spectroscopy.
