▎ 摘　　要

NOVELTY - Preparing of nitrogen doped grapheme by electrochemistry stripping comprises (a) taking graphene oxide ultrasonic dispersing in water to obtain dispersion liquid, (b) taking obtained graphene oxide liquid and crosslinking agent, mixing, (c) taking the obtained mixed liquid into a hydro-thermal reaction kettle, hydro-thermal under certain temperature, crosslinking to obtain graphene crosslinking hydrogel, (d) taking the obtained product, drying to obtain crosslinking agent supporting xerogels, (e) taking the obtained product, under certain nitrogen protection, sintering at certain temperature. USE - The method is useful for preparing of nitrogen doped grapheme by electrochemistry stripping super capacitor electrode material (claimed). ADVANTAGE - The nitrogen doped grapheme by electrochemistry stripping: has stable three-dimensional porous structure.
