A Comparison of Two-Way (Chemical and Thermal) Synthesis and Characterization of Graphene Oxide (GO) and Reduced Graphene Oxide (rGO)

Graphene oxide (GO) was prepared by two methods; Modified Hummer’s as well as Improved Hummer’s methods. Similarly reduced graphene oxide (rGO) was also prepared by two methods namely chemical and hydrothermal methods. Chemically rGO was prepared using urea and aluminium powder while hydrothermally rGO was prepared using autoclave and hot air oven. The sample obtained were characterized using UV-Visible, FTIR, XRD and Raman spectroscopy. The result of the given samples obtained by the above methods for GO and rGO were compared and analyzed which showed that the hydrothermal route is better due to its simplicity and non-toxicity than chemical route but used for small scale production. These findings highlight the advantages of the hydrothermal method for GO and rGO synthesis, providing valuable insights for future research and development in graphene-based materials.
