Graphene and Graphene Oxide

Graphene is a carbon based material that can be viewed as a one atom thick sheet of graphite and has been investigated intensely in recent years following a report by Novoselov et al. on its isolation and measurement of its unique electronic properties.1 Quickly after its initial discovery, graphene was used to make electronic devices for a variety of applications.2 Because high quality sheets of graphene is often prepared by chemical vapor deposition (CVD),3,4 which requires expensive equipment, many groups have looked at using graphene oxide as a solution processable alternative for the preparation of graphene like materials.5,6,7 Indeed, graphene oxide can be reduced in solution and as a thin film using a variety of reducing conditions, and reduction converts the graphene oxide into a material that has a large enhancement in electrical conductivity.7,8 In addition to its use in making reduced graphene oxide for electronic devices, graphene oxide has been used in catalytic oxidation9,10,11 biotechnology12,13,14,15 and as a surfactant.16 Graphene is also related to carbon nanomaterials such as carbon nanotubes and fullerene.
