▎ 摘　　要

NOVELTY - Preparation of foam nickel/graphene nano-gold composite with three-dimensional structure, involves preparing 0.1-5 mg/ml aqueous graphene oxide solution, adding foam nickel to graphene oxide aqueous solution, ultrasonically processing to obtain graphene oxide loaded with foam nickel, drying to obtain foam nickel-graphene oxide composite, soaking the composite in chloroauric acid solution, adding sodium citrate solution, reacting at 60-200 degrees C for 1-5 hours, cooling, separating, washing, and drying. USE - Preparation of foam nickel/graphene nano-gold composite with three-dimensional structure (claimed). ADVANTAGE - The method effectively reduces stacking of reduced graphene oxide and irreversible agglomeration, enables size control of gold particles at nano level, and improves the electrocatalytic activity of gold nanoparticles.
