From last two decades, the use of various carbonaceous materials attract immense attention in the field of material science and organic synthesis. The diverse use of carbon allotrope and its functionalized materials is also noteworthy. In this book, we discuss about the physical and chemical properties of some carbon rich materials. The use of graphene and G-based materials is discussed by the authors. Supercapacitors are also made from graphene based materials and which is discussed in this book. The catalytic applications of graphene oxide in various multicomponent reactions is clearly represented. Authors also describe the diverse use of fullerene based materials and carbon nanotubes. We hope the rich contents of this book may be beneficial for readers.
