NOVELTY - A hydrogenated graphene is prepared by taking sodium-potassium alloy and anhydrous liquid amine, mixing in inert atmosphere, adding graphite fluoride dispersion, mixing to react for 1-15 hours, adding fatty alcohol, and quenching reaction. Graphite fluoride dispersion is prepared by suspending graphite fluoride in liquid amine. USE - Method for preparing hydrogenated graphene (claimed). ADVANTAGE - The simple and efficient preparation has mild reaction conditions and low cost. The hydrogenated graphene has adjustable band gap.
