Graphene1 is a distinct allotrope of carbon. The Nobel Prize in Physics was awarded to Prof. A. K. Geim and K. Novoselov in 2010 for their research on graphenes. Other allotropes of carbon that have received considerable attention and are of interest are as follows: (1) graphite;2 (2) diamond;3 (3) fullerene,4 C60; and (4) carbon nanotubes (CNTs).5 Graphite was discovered in 1564. The energy that binds the interlayer graphene sheets is around 5.9 kJ mol-1. Graphene can be obtained by exfoliating layers from the bonded sheets down to one layer. ...
