Using HRTEM, XRD and Raman spectroscopy we demonstrated a polyhedral multi-shell fullerene-like structure of astralen particles. The polyhedra consist of large defect-free flat graphitic faces connected by defective edge regions with presumably pentagon-like structure. The faces comprise a stacking of 20–50 planar graphene sheets with inter-sheet distance of ~0.340 nm. Average sizes of the particles...
