NOVELTY - Rapidly preparing silver nano-scale-graphene-foamed nickel composite comprises (i) preparing graphene coated nickel foam material, (ii) adding ethylene glycol into reactor, heating under oil bath, then adding sodium sulfide and ethylene glycol mixed solution, adding mixed solution of polyvinylpyrrolidone and ethylene glycol, then adding mixed solution of silver nitrate and ethylene and heating, (iii) preparing silver nano particle-graphene-nickel foam composite material, and (iv) placing silver nano particle-graphene-nickel foam composite material in a vacuum tube furnace and annealing. USE - The method is useful for rapidly preparing silver nano-scale-graphene-foamed nickel composite (claimed). DETAILED DESCRIPTION - Rapidly preparing silver nano-scale-graphene-foamed nickel composite comprises (i) washing nickel foam with acetone, ethanol and deionized water to removing the surface oxide layer and then dried with nitrogen, placing into vacuum tube furnace tube vacuum, then removing the tube of air, passing argon and hydrogen gas, heating to 900-1000 degrees C and annealing, then introducing methane gas and hydrogen gas during growing a graphene, growth is cut off after methane gas and furnace cooling to room temperature, then removing out the sample to obtain graphene coated nickel foam material, (ii) adding ethylene glycol into reactor, heating under oil bath, then adding sodium sulfide and ethylene glycol mixed solution, then adding mixed solution of polyvinylpyrrolidone and ethylene glycol, adding mixed solution of silver nitrate and ethylene, insulating, heating under water bath is 20-25 degrees C for 20 minutes, then performing centrifugation with acetone and deionized water to obtain silver nano particle, (iii) diluting silver nano particle and subjecting to ultrasonic dispersion and pouring the mixture into reactor containing the magnetic particles, then immersing graphene-foamed nickel prepared by chemical vapor deposition method obtained in step (i) in a reactor containing silver nano particle, heating reaction under oil bath, then removing sample, rinsing with deionized water and drying to obtain silver nano particle-graphene-nickel foam composite material, and (iv) placing silver nano particle-graphene-nickel foam composite material obtained in (iii) in a vacuum tube furnace, evacuating and annealing to obtain final product.
