Abstract

Carbon micro-coils were obtained by the Ni catalyzed pyrolysis of propane as a carbon source which was pre-heated and pre-pyrolyzed at 1000–1100 °C. The obtained carbon micro-coils were mostly irregular double coils with a larger coil pitch of 1–5 μm and larger coil diameter of 5–20 μm than that obtained using acetylene.
