Compositions of carbonaceous nanoparticle fabrication and their use for electrode materials in supercapacitors are provided. The supercapacitor includes a first electrode having a first substrate and carbonaceous nanoparticles; a second electrode comprising a second substrate and carbonaceous nanoparticles; a separator positioned between the first electrode and the second electrode; and an electrolyte. Methods of making an electrode for a supercapacitor are also provided.

Carbonaceous nanoparticles, methods of making same and uses thereof

Methods and compositions of carbonaceous nanoparticle fabrication and their use for electrode materials in supercapacitors are provided. The method includes a first step of reacting a first carbon source with a second carbon source in the presence of a nitrogen source in a DC arc furnace to form a composite nanoparticle. The second carbon source includes a dopant. The composite nanoparticle includes a crystalline carbon phase having an amorphous phase comprising dopant or carbide. The method includes a second step of removing the amorphous second layer to form the carbonaceous nanoparticle.
