Graphene oxide (GO), a nonstoichiometric, two-dimensionalcarbonsheetresultingfromacidexfoliationofgraphite,offersa new class of solution-dispersible polyaromatic platform forperforming chemistry. Graphene oxide bears covalentlybound epoxide (1,2-ether) and hydroxyl functional groupson either side of its basal plane, while carboxyl groups arelocated at the edge sites.
