摘要： The present invention relates to a method for the aerosol synthesis of carbon nanostructures under atmospheric pressure comprising a spark generation step of generating a spark between a graphite electrode made of carbon and a metal electrode made of a catalytic metal inducing the graphitization of carbon and vaporizing the carbon component of the graphite electrode and the metal component of the metal electrode utilizing the heat produced by the spark, thereby generating carbon vapor and metal vapor; and a carbon nanostructure generation step of cooling and condensing the carbon vapor and the metal vapor to form a graphitic carbon layer and catalytic metal particles and generating carbon nanostructures in which the graphitic carbon layer grows on the surface of the catalytic metal particles and covers the catalytic metal particles.
