Abstract
The method of making a porous nitrogen-doped carbon electrode from biomass is a chemical activation-based method of making a porous graphite carbon electrode for supercapacitors and the like. Date palm pollen grains are used as a precursor biomass carbon source for producing the porous graphite carbon. A volume of date palm (L.) pollen grains is mixed into an aqueous solution of potassium hydroxide to produce a precursor carbon solution. The precursor carbon solution is dried to produce precursor carbon, and the precursor carbon is heated in an inert atmosphere to produce porous nitrogen-doped graphite carbon. The porous nitrogen-doped graphite carbon is washed, dried and mixed with a polyvinylidene difluoride binder, carbon black, and a solvent to form a slurry. The slurry is then coated on nickel foam to form a porous nitrogen-doped carbon electrode. The porous nitrogen-doped carbon electrode is dried, weighted and pressed into a sheet electrode.
