▎ 摘　　要

NOVELTY - Preparing a three-dimensional graphene-foam nickel composite material comprises taking foam nickel as template, taking carbon hydrogen gas methane as C source, reducing atmosphere under the protection, synthesizing uniform distribution in a tube furnace using chemical vapor deposition method, where the three-dimensional graphene-foam nickel composite material is having a uniform thickness, generating composite material in foam nickel on the surface of graphene material nano-layer structure. USE - The method is useful for preparing a three-dimensional graphene-foam nickel composite material. ADVANTAGE - The material is small, and has good anti-interference performance and good in reproducibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for glucose electrochemical sensor electrode, comprising performing a perforation cut on a three-dimensional graphene-foam Ni composite material by a puncher, cutting whole electrochemical sensor electrode strip, electrically connecting to one end of electrochemical sensing electrode through lead, and insulating encapsulating the one end enveloping area by epoxy resin, leaving the other end of conductive sensing area to obtain glucose electrochemical sensor electrodes.
