NOVELTY - Nitrogen-doped spherical porous carbon comprises 80-99 wt.% porous carbon and 1-20 wt.% graphene nanoribbons. USE - Nitrogen-doped spherical porous carbon. ADVANTAGE - The nitrogen-doped spherical porous carbon adopts soft template hole and nitrogen element doping mode, to improve the adsorption performance and service life of the spherical porous carbon, and strengthens the adsorption effect to the sub-micron and the following adsorption quality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a nitrogen-doped spherical porous carbon, which involves: a. dispersing graphene nanoribbons in a solvent in which a polymer and dissolving organic pore-forming agent to obtain a polymer precursor solution; b. spray drying the polymer precursor liquid to obtain solid spherical particles; and c. subjecting solid spherical particles to high-temperature carbonization and naturally cooling to room temperature to obtain product.
