▎ 摘　　要

NOVELTY - Producing biomass-assisted nitrogen-doped graphene involves ultrasonically dispersing graphene oxide powder, adding biomass raw material powder to graphene oxide powder, and then ultrasonically dispersing obtained mixture. Nitrogen source material is added to obtained mixture, and then dispersed to obtain mixed solution. The carbonization of mixed solution is carried out, and then carbonized material is washed and milled in ball mill to obtain biomass-assisted nitrogen-doped graphene. USE - Method for producing biomass-assisted nitrogen-doped graphene used for super capacitor electrode material (claimed). ADVANTAGE - The method enables to produce biomass-assisted nitrogen-doped graphene in a simple manner.
