▎ 摘 要
NOVELTY - Preparation of fluorinated graphene and lithium fluoride comprises feeding graphene oxide into fluorination furnace, vacuuming furnace, adding fluorine-containing gas, and heating at 400-550 degrees C to carry out fluorination; and cooling to obtain fluorinated graphene, passing fluorine-containing gas through lithium hydroxide solution to carry out absorption reaction, adjusting pH value of system to 2-3, and reacting to separate lithium fluoride. USE - Method for preparing fluorinated graphene and lithium fluoride (claimed). ADVANTAGE - The product has high purity, and good economic benefits. The method is environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device for preparing fluorinated graphene and lithium fluoride comprising fluorination furnace body, absorption device, gas inlet outlet, gas distribution plate, and air cavity.
