Graphene and Fullerenes

Graphene and fullerenes are nanoscale allotropes of carbon. 

Graphene is a two-dimensional sheet, which can be named as “two-dimensional hexagonal lattice” which is a flat sheet of carbon atoms arranged in hexagons. Moreover, it is an infinitely large aromatic molecule.

Fullerenes are molecules of carbon in the shape of spheres, ellipses and tubes. Unlike graphene, fullerene is a 3D structure. Furthermore, it occurs as a large spheroidal molecule, and it consists of a cage formed by sixty or more atoms.
