ABSTRACT
Graphene, a one-atom thick planar sheet of sp2-bonded carbon atoms packed in a honeycomb lattice, is considered to be the mother of all graphitic materials and created tremendous interest to both physicist and chemist. Graphene and its derivative have potential applications in nanoelectronics, supercapacitors, solar cells, batteries, flexible displays, hydrogen storage, waste-water treatment, and sensors. In this chapter, a brief overview on various aspects of graphene such as discovery, synthesis, functionalization, composites, and its applications in removal and detection of aqueous inorganic pollutants had been illustrated.
