Graphite to graphene
Did you know?
WebA layer of graphite is called graphene. Graphene is produced through layers of graphite compound exfoliated layer by layer until what remains is a ‘honeycomb’ carbon sheet. In layman’s terms, a stack of graphene is graphite. The discovery of graphene started long before the extraction and characterization of graphene (Novoselov et al. 2004).
