The electronic structure of hollow graphitic carbon nanoparticles obtained by catalytic graphitization of acetylene carbon black (ACB HGCNs) was studied by ultra-soft X-ray emission spectroscopy (USXES) method. The phases of the carbon powder samples were determined by XRD with monochromatic
CuKα1 radiation. Transmission electron microscopy was used to study the ACB HGCN spatial structures and morphologies. The electronic structures of reference Q-graphenes and HGCNs obtained from iron carbide filled carbon nanocapsules (Fe3C@CNCs) which were synthesized by plasma method in hexane were measured for comparison with that of the synthesized ACB HGCNs
