Abstract
A method for manufacturing a porous carbon material doped with a heterogeneous element and a porous carbon material doped with a heterogeneous element manufactured using the method are proposed. The method includes melting carbon precursor powder that contains one or more kinds of heterogeneous elements selected from metal and nonmetal to prepare a precursor melt; disposing a pair of metal wires in the precursor melt; and applying power to the metal wires to perform plasma-discharge, thus forming and aggregating carbon nanoparticles doped with the heterogeneous element while having a micropore and thereby forming a porous carbon material having a meso-macro hierarchical pore structure. As the heterogeneous element is bound to carbon of the carbon precursor, the carbon nanoparticles are formed in an amorphous structure while being doped with the heterogeneous element, thus increasing an active site.
