Abstract

Numerous techniques for the purification of chemically synthesized graphene have been investigated, exploiting the relative aqueous solubilities of the impurities and carbon sheets. This demonstrates that simple aqueous washing provides a reliable platform for the purification of graphene, without the need for harsh chemical treatments. The presence of cavities or pores in the as-obtained graphene structure are believed to inhibit small particles, that are interspersed throughout the material, from undergoing hydrolysis reactions.
