HYDRO-SOLVO-THERMAL GRAPHENE OXIDE SYNTHESIS METHOD

摘要

The present invention relates to a hydro-solvo -thermal graphene oxide synthesis method to obtain potassium-doped graphene oxide for bio-sensing and bio-imaging of natural occurring source. The method includes solvothermal grinding of the Quercus ilex fruit in a solvent mixture to obtain a crushed extract paste, synthesizing the crushed extract paste to obtain a brown solid residue, coefficient separating of the brown residue to obtain the uniform brownish solution, nano filtering to obtain a clear brownish solution and drying the clear brownish solution to obtain a dried brown solid of potassium-doped graphene oxide.
