Hydrothermal reduction of graphene oxide (GO) produced graphene quantum dots (GQDs) along with porous reduced graphene (PGs). The removal of nano sized GQDs generate several round shaped edges in the graphene, which facilitated improved charge storage. In addition to preparation of porous graphene, we developed an approach to process the PGs. We envisioned preparing conjugated polymer as processing material. The capacitive behavior of PGs was characterized using cyclic voltammetry (CV) and galvanostatic charge?discharge (GCD) techniques. The specific capacitance of hydrothermally reduced GO (PGs) and PGs?PANI composites was 185 F/g and 357 F/g at 0.1 A/g in 1 M H2SO4 electrolyte. The energy density of PGs?PANI composite was obtained 49.58 W h/kg at a power density of 71.8 W/kg.1 aChini, Mrinmoy, Kumar1 aChatterjee, Shyambo  uhttps://library.ncl.res.in/content/hydrothermally-reduced-nano-porous-graphene%E2%80%93polyaniline-nanofiber-composites-supercapacitor
