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.

我们通过磁感应作用将甘油和二茂铁共热解，进行了磁性碳纳米颗粒（M-CNPs）的受控合成。通过透射电子显微镜证实了所合成的M-CNP的形态，并使用热重分析法分析了碳和铁的含量。还使用AC磁化率分析仪检查了对磁刺激有反应的M-CNP。我们对700-1000°C范围内合成温度影响的研究表明，初始甘油与二茂铁的重量比为3：1，温度为800°C时，M-CNPs的收率最高。比较有磁感应和无磁感应的合成，在磁感应影响下的受控合成显示出有望作为高产量生产高质量M-CNP的方法。
