▎ 摘 要
NOVELTY - Method for rapidly reducing graphene oxide without impurities, involves (a) placing graphene oxide in a vacuum drying oven, and vacuuming the drying oven at room temperature, (b) maintaining the temperature of vacuum oven at 150-300 degrees C and heating the graphene oxide, (c) maintaining the temperature of oven for 0.5-5 hours, and completely heating the graphene oxide, (d) stop heating, reducing the temperature of oven to room temperature, opening the vacuum valve and collecting the powder to obtain the reduced impurity-free graphene oxide. USE - The method is used for preparing impurity-free reduced graphene oxide (claimed).
