Abstract
The present invention discloses a simple and easily scalable process for preparation of two potentially value added carbonaceous materials from graphene. The invention further discloses simultaneous preparation of graphene quantum dots (GQDs,) and porous graphene (pGr) from graphene. The invention further relates to nitrogen doped porous graphene having excellent activity towards electrochemical oxygen reduction reaction (ORR).
