NOVELTY - Preparing in-situ synthesized three-dimensional graphene/one-dimensional carbon nanotube-supported copper nanoparticle material comprises (i) taking copper nitrate powder, anhydrous glucose powder and sodium chloride in a mass ratio of (1.8-2.2):1:(36-37), dissolving in deionized water to obtain homogeneous mixed solution, (ii) freeze-drying and grinding to obtain mixed powder, (iii) placing mixed powder in a quartz ark, then placing in the constant temperature zone in the middle of a tube furnace, increasing the temperature to 730-750 degrees C under the protection of hydrogen, insulating, stopping passing of hydrogen gas, introducing mixed gas of acetylene and argon gas, insulating, stopping passing of acetylene, and cooling to room temperature under argon atmosphere to obtain copper-graphene/carbon nanotube composites with sodium chloride as template, and (iv) removing sodium chloride template, and drying. USE - The method is useful for preparing in-situ synthesized three-dimensional graphene/one-dimensional carbon nanotube-supported copper nanoparticle material.
