Graphene: The two-dimensional carbon nanomaterial

UjjalKumar Sur

Graphene, the name is given to the two-dimensional sheet of sp2-hybridized carbon. Its extended honeycomb network is the basic building block of other important carbon allotropes; it can be stacked to form 3D graphite, rolled to form1D carbon nanotubes, and wrapped to form0Dfullerenes. Therefore, graphene is called the mother of all graphitic carbon based nanomaterials. This review article summarizes the various aspects of graphene which includes synthesis, some of its amazing properties and its various applications ranging from sensors to energy storage devices.
