Production of graphene through a two-step reduction (2012)

Abstract:
-Graphene, a precursor to all carbon allotropes in terms of unit of formation, is a two dimensional single layered sheet of carbon in the shape of a honeycomb lattice, with properties surpassing that of other nanomaterials like fullerene and carbon nanotubes. The reduction of graphene oxide is one of the commonly used methods in the production of low cost graphene. This study aimed to compare the graphene formed from a two-step reduction method with those formed from two separate single step reduction methods of graphene oxide from commercial graphite, as well as determine the effects of the oxidation temperature, microwave power and microwave exposure time to the characteristics of the graphene form. The reduced graphene oxide was evaluated based on the resulting C:O ratios and subjective analysis of the images obtained from characterization using SEM/EDX. Based on the results, the data was inconclusive and should be subjected to further analysis.
