Fe3C–C core–shell nanoparticles were fabricated on a large scale by metal-organic chemical vapor deposition at 700 °C with ferric acetylacetonate as the precursor. Analysis results of x-ray diffraction, transmission electron microscope and Raman spectroscope showed that the Fe3C cores with an average diameter of ~35 nm were capsulated by the graphite-like C layers with the thickness of 2–5 nm. The comparative experiments revealed that considerable Fe3O4–Fe3C core–shell nanoparticles and C nanotubes were generated simultaneously at 600 and 800 °C, respectively. A formation mechanism was proposed for the as-synthesized core–shell nanostructures, based on the temperature-dependent catalytic activity of Fe3C nanoclusters and the coalescence process of Fe3C–C nanoclusters. The Fe3C–C core–shell nanoparticles exhibited a saturation magnetization of 23.6 emu g−1 and a coercivity of 550 Oe at room temperature.
