NOVELTY - Preparing high dispersibility graphite alkene, comprises (i) adding graphene and 4-aminopyridine into hydrochloric acid, ultrasonically dispersing uniformly, adding sodium nitrite aqueous solution to ultrasonically disperse uniformly in an environment of 0-5 degreesC, adding sodium hydroxide and ultrasonically dispersing; and (ii) adding excess dilute hydrochloric acid to neutralize the residual sodium hydroxide in the solution, filtering to obtain a precipitate, washing and drying the precipitate graphene. USE - The graphite alkene is useful for catalysis, electrochemical, biological medicine and solar battery. ADVANTAGE - The graphite alkene has high dispersibility in aqueous solution; is not easy to agglomerate; utilizes low cost raw material. The method is simple and economical.
