제목 | The effect of metal nanoparticles on the exfoliation of graphite to graphene |
초록 | While various attempts have been made to obtain graphene effectively from graphite over the past decades, they have some limitations. For example, well-known reduction processes from graphene oxide result in defects across the graphene layer and the use of hazardous and explosive reducing agents is also problematic. In this context, exfoliation from graphite by sonication is expected to provide a more non-destructive and safe way for synthesizing graphene. In this work we developed a new exfoliation method using metal nanoparticles. It was observed that the formation and growth of nanoparticles from the metal ions between the carbon layers at a proper condition enhanced the exfoliation of graphite.
