▎ 摘  要

NOVELTY - Method for producing reduced graphene oxide, involves preparing an aqueous dispersion of graphene oxide having a specific surface area of greater than or equal to 600 m2/g calculated by methylene blue adsorption method, adding 10-50 wt.% ascorbic acid to graphene oxide, adding hydrazine, and performing heating reduction. USE - The method is used for producing reduced graphene oxide for electrode of electric double layer capacitor having low manganese content and large specific surface area. ADVANTAGE - The reduced graphene oxide has large specific surface area and reduced amount of manganese.
