▎ 摘 要
NOVELTY - Method for reducing graphene involves (i) dispersing graphene oxide in deionized water in a three-necked flask equipped with a mechanical mixing oil bath heating device, adding hydrazine hydrate under the action of mechanical stirring condition, where the mass ratio of graphene oxide and hydrazine hydrate is 1:2, (ii) heating the oil bath at 95-100 degrees C for 24 hours, and (iii) centrifugally washing the prepared black product with ionic water to a pH value of 7. USE - The method is useful for reducing graphene. ADVANTAGE - The method has simple operation and easy temperature control.
