▎ 摘  要

NOVELTY - Method for preparing graphene nitrogen-doped porous carbon material by taking melamine, polyvinylpyrrolidone and ammonium chloride as raw materials, mixing and grinding at a certain ratio to obtain a mixture, and calcining the obtained mixture in an air atmosphere to obtain the product. USE - The method is useful for preparing graphene nitrogen-doped porous carbon material for supercapacitor and organic pollutant adsorption (all claimed). ADVANTAGE - The method uses direct calcination without drying to shorten and simplify the preparation cycle, and is convenient. The carbon material has excellent electrochemical and adsorption properties.
