NOVELTY - Manufacturing nitrogen-doped porous graphene involves preparing an aqueous solution containing graphene oxide involves etching the graphene oxide with an etchant to produce porous graphene oxide in which one pore is formed, and adding a nitrogen-containing precursor to the porous graphene oxide to form a porous pyridine-N-doped graphene structure by reduction reaction and nitrogen doping (N-doping) for 1-2 hours 30 minutes. USE - Method for manufacturing nitrogen-doped porous graphene. ADVANTAGE - The method enables to manufacture nitrogen-doped porous graphene which is helps to improves durability and shows a significant increase in catalytic activity.
