▎ 摘　　要

NOVELTY - Preparing a oxidation graphene/carbon nano tube-nano nickel electrode, comprises (a) dispersing graphene oxide and carbon nanotubes in deionized water to obtain graphene oxide/carbon nanotube mixed solution, (b) swelling the acrylic acid cross-linked resin and polyoxyethylene polypropylene tri-block polymer in the deionized water and obtaining acrylic acid cross-linked resin/polyoxyethylene polypropylene tri-block polymer mixed gel, (c) adding the nano-nickel powder into mixed solution of oxidized graphene carbon nanotubes, stirring uniformly, then adding the acrylic acid cross-linked resin/polyoxyethylene polypropylene triblock polymer to gel, uniformly mixing to obtain the oxidized graphene/carbon nano-tube-nano-nickel composite ink, (d) placing the oxidized graphene/carbon nano-tube-nano-nickel composite ink into 3D printer and taking glass sheet as substrate for 3D printing to obtain oxidized graphene/carbon nano tube-nano nickel composite hydrogel, and (e) freezing and drying. USE - The oxidation graphene/carbon nano tube-nano nickel electrode is useful for electrolyzing water under alkaline condition (claimed). ADVANTAGE - The electrode: has low driving potential of alkaline electrolytic water, excellent catalytic performance, corrosion resistance and circulation stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a oxidation graphene/carbon nano tube-nano nickel electrode.
