▎ 摘　　要

NOVELTY - The shape involves preparing a graphene oxide water dispersion. A nano silicon dioxide dispersion is mixed with the graphene oxide water dispersion solution obtain to silicon dioxide i.e. doped with the graphene oxide. A hydro-thermal process is mixed for preparing reduction-oxidation graphene of a silicon dioxide as template doped gas gel. The silicon dioxide is obtained for dehydrating and drying below a graphene air gel doped from graphene composite film. A nickel is coated uniformly to obtain a foam nickel surface. The graphene nano electrode material is obtained in a controllable shape. USE - Graphene nano electrode material for controllable shape in preparation method. ADVANTAGE - The shape enables ensuring better controllability of reduction-oxidation graphene air gel, and improving graphene nano electrode material of graphene air gel. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene nano electrode material for controllable shape in preparation method.
