This is a novel method used to synthesize herringbone-stacked carbon nanofibers in high selectivity using cobaltocene as the catalytic precursor. Thiophene is essential for CNF growth while hydrogen is used as carrier gas at 1100 °C. The conversion rate of the CNFs collected in the cold trap is approximately 1.5 wt% of the initial precursor. The effects of the catalytic precursor temperature, thiophene and acetylene are the parameters that decide the diameter and selectivity of CNF.
