Highlights

    • Controlled synthesis of magnetic carbon nanoparticles (M-CNPs) was achieved. • M-CNPs were synthesized via co-pyrolysis of glycerol and ferrocene. • At 800 °C glycerol to ferrocene ratio of 3:1 high yield of M-CNPs was obtained.

Abstract

We performed a controlled synthesis of magnetic carbon nanoparticles (M-CNPs) via co-pyrolysis of glycerol and ferrocene with magnetic induction. The morphology of the synthesized M-CNPs was confirmed by transmission electron microscopy, and thermogravimetric analysis was used to analyze the carbon and Fe contents. M-CNPs that responded to magnetic stimulation were also examined with an AC-magnetic susceptibility analyzer. Our investigations on the influence of synthesis temperature in the range 700–1000 °C suggested that for an initial glycerol to ferrocene weight ratio of 3:1 and a temperature of 800 °C gave the highest yield of M-CNPs. Comparing the synthesis with and without magnetic induction, the controlled synthesis under the influence of magnetic induction shows promise as a method for producing high quality M-CNPs in high yields.
