Abstract

The invention relates to a method for preparing a carbon nanohorn metal composite material using alternating current, comprising the following steps: providing two electrodes whose tops correspond to each other, and the two electrodes are graphite electrodes and metal electrodes respectively; generating stable electricity between the two electrodes AC arc; two electrodes are connected with 10‑1500A AC power supply; the present invention realizes the alternate consumption of two electrodes by adopting AC power supply, and prolongs the reaction time of a single preparation; under the high temperature of the arc, graphite electrodes and metal Co-evaporation of the opposite surfaces of the electrodes produces carbon ions and metal particles, and the carbon ions and metal particles wrap each other to form a carbon nanohorn technology composite material. The collision chance of the metal particles increases the output rate of the carbon nanohorn metal composite material and the purity of the product.
