▎ 摘　　要

NOVELTY - Three dimensional reduced graphene oxide or nano metal silver aerogel, is claimed. The third dimension porous structure hydro gel is reduced graphene oxide alkene layer and uniformly loading on reducing oxidation graphene sheet layer or the poly-crystalline nano silver metal. USE - Used as three dimensional reduced graphene oxide or nano metal silver aerogel. ADVANTAGE - The reduced graphene oxide or nano metal silver aerogel is prepared by simple preparation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene oxide or nano metal silver aerogel comprising (i) mixing soluble silver salt aqueous solution and graphene oxide aqueous solution uniformly to obtain precursor solution, (ii) adding reducing agent drop wise into the precursor solution and reacting under room temperature to obtain the three dimension reduced graphene oxide or nano metal silver aerogel, (iii) washing the three dimension reduced graphene oxide or nano metal silver aerogel and drying to obtain the three dimension reduced graphene oxide or nano metal silver aerogel.
