The invention discloses a method and a device for preparing carbon-coated copper nanoparticles by using a metal wire electric explosion method. A copper wire with a certain length and diameter is evenly wound on a carbon rod, and the metal wire is passed through in an argon atmosphere. High voltage and high current make the wire explode electrically, and the carbon-coated copper nanoparticles can be collected. The copper wire undergoes phase transformation during heating during the electric explosion, and undergoes melting, gasification, plasma and other processes successively, and produces copper atoms under the high temperature heating of the plasma, and a part of carbon atoms will also be formed after the carbon rod is passed through a high current. , and then the two spontaneously and uniformly nucleate and condense into atomic clusters from the gas phase, forming an initial small droplet, which grows continuously, and then forms a carbon coating layer through two mechanisms of internal carbon atom precipitation and external carbon atom deposition, and finally passes through Cooling forms carbon-coated copper nanoparticles. This method proposes a new method for preparing carbon-coated copper nanoparticles, which has great application value for industrial production and scientific research.
