▎ 摘　　要

NOVELTY - Preparing graphene/hydroxycarbonate nano composites comprises (i) dissolving metal salt in polyhydric alcohol, where the metal salt concentration in the solvent is 0.01-0.05 mol/l, and (ii) adding graphene powder to the step (i) resulting solution and sonicating for 1-6 hours to prepare a graphene suspension having concentration of 1-10 g/l, adding equal volume of aqueous ammonia, heating to 100-200 degrees C, reacting for 1-24 hours, cooling, washing, and drying to obtain graphene/hydroxycarbonate nano composites. USE - The nano composites material is useful in photocatalysis, super capacitors and secondary battery field. ADVANTAGE - The method is simple.
