▎ 摘　　要

NOVELTY - A microwave-assisted sodium citrate reduction method for preparing graphene comprises using Hummers method to prepare 0.05-0.3 g graphite oxide and dispersing in 200 mL deionized water, and ultrasonically dispersing at 210-300 W for 40-80 minutes; adding 1-30 g sodium citrate, putting in microwave reactor, and reacting at 70-95 degrees C for 60 seconds at stirring speed of 600 revolutions/minute (rpm); and cooling to room temperature, centrifuging at 13000 rpm and 3 times cleaning, freezing and drying to obtain graphene. USE - Method of microwave-assisted sodium citrate reduction for preparing graphene (claimed). ADVANTAGE - The method is fast and energy-saving, has environmental protection and high efficiency, prepares uniform size distribution and excellent electrical performance graphite, and provides technical assurance for application of graphite. DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram illustrating a microwave-assisted sodium citrate reduction method for preparing graphene.
