▎ 摘  要

NOVELTY - Preparation of three-dimensional nitrogen-doped graphene with polybenzimidazole-like macromolecules comprises deacidifying rigid aromatic polybenzimidazole molecule polymer, stirring with template agent, evaporating solvent, vacuum-drying, grinding, entering into high temperature furnace, performing pyrolysis under protection of argon gas for 2-3 hours, cooling, removing template by diluted hydrofluoric acid or hydrochloric acid and activating. The polybenzimidazole molecule polymer is rigid aromatic benzimidazole, imidazole-containing molecules and amino-terminated nitrogen-rich element. USE - Method for preparing three-dimensional nitrogen-doped graphene with polybenzimidazole-like macromolecules (claimed) used for catalysis and electrolysis of water oxygen evolution reaction catalyst for fuel battery, metal air battery, electrolytic supercapacitor electrode material, lithium ion battery and sensor.
