Abstract
A method includes: supplying sources or nanoparticles of any one or two or more combinations selected from a group which consists of a carbon source, a doping source, a doped element containing carbon source, and a waste plastic source into a high-temperature and high-pressure closed autoclave, completely closing the high-temperature and high-pressure closed autoclave, and forming a nanoparticle-carbon core-shell structure by a single process by coating a carbon layer on the surface of the nanoparticles or forming a core-shell structure of nanoparticle-doped carbon by the single process by coating a carbon layer doped with the doped element on the surface of the nanoparticles under pressure self-generated in the autoclave and a reaction temperature in the range of 500 to 850° C. by heating the autoclave.
