▎ 摘  要

NOVELTY - Manufacture of multi-stage through-hole three-dimensional nitrogen-doped graphene porous carbon involves regularly-arranging rigid poly(2,5-benzimidazole) solution on a surface of a nano-calcium carbonate template, pyrolyzing under inert gas atmosphere for 2-3 hours in high-temperature furnace to produce carbon dioxide which forms a small through-hole between the templates, removing the nano-template using dilute hydrochloric acid, forming three-dimensional nitrogen-doped graphene between the pores through a small hole. USE - Manufacture of multi-stage through-hole three-dimensional nitrogen-doped graphene porous carbon used as catalyst for redox reaction and electrolysis of water and oxygen precipitation reaction, and electrode material for metal air battery, fuel cell and supercapacitor (all claimed). ADVANTAGE - The method enables efficient manufacture of multi-stage through-hole three-dimensional nitrogen-doped graphene porous carbon with high calcium-carbonate decomposition rate and improved mass transfer effect.
