The onion-like carbons (OLCs) were synthesized from the mixtures of gaseous methane, benzene and oxygen by a shock-wave induced rapid chemical chain reaction under extreme conditions (at high temperatures and pressures). The OLCs consisting of spherically concentric graphitic shells with sizes of about 5–30nm were obtained. The morphology and structure of the products were studied by XRD analysis, TEM, EDX and Raman spectroscopy.
