Nitrogen-doped nanoporous carbons were synthesized by a solvent-free mechanochemically induced one-pot synthesis. This facile approach involves the mechanochemical treatment and carbonization of three solid materials: potassium carbonate, urea, lignin, which is waste product from pulp industry. The resulting nitrogen-doped porous offer very high specific surface area up to 3000 m2 g-1 large pore volume 2 cm3 . reaction impact activation functionalization are investigated nitrogen water physisorption high-resolution X-ray photoelectron spectroscopy (XPS). Our N-doped highly suitable for electrochemical energy storage as supercapacitor electrodes, showing capacitances in aqueous 1 m Li2 SO4 electrolyte (177 F ), organic tetraethylammonium tetrafluoroborate acetonitrile (147 an ionic liquid (1-ethyl-3-methylimidazolium tetrafluoroborate; 192 ). new pathway synergistically combines attractive energy-storage ratings with scalable, time-efficient, cost-effective, environmentally favorable
