Claim:
1. An in-situ process for simultaneous synthesis of nanoporous graphene (pGr) and photo luminescent graphene quantum dots (GQDs) with no wastage of carbonaceous material comprising; i. dispersing graphene with 25-35% hydrogen peroxide (H ii. filtering the resulting mixture to obtain the solution of GQDs as filtrate and residue of pGr; iii. drying the residue as pGr as obtained in step (ii) at a temperature in the range of 40° C.-60° C. for 1-3 h; iv. dialysing the filtrate as obtained in step (ii) in dialysis bag for 1-3 days at 27 to 30° C. to obtain solution of GQD; v. nitrogen doping of the porous graphene as obtained in step (iii) to obtain nitrogen doped porous graphene.
