We report a simple solvothermal method for the synthesis of monodisperse magnetite nanoparticles with a controlled particle size within the range of 40 to 200 nm from available and inexpensive single iron precursor (FeCl₃) and, as co‐capping agents, sodium acetate and ethylene diamine. The particle size can be easily controlled by the reaction time of synthesis. Transmission electron microscopy, x‐ray diffraction, Fourier transform infrared spectroscopy, and x‐ray photoelectron spectroscopy techniques were used to investigate the obtained particles. The results revealed that the resulting iron oxide particles exhibit a single magnetite Fe₃O₄ phase and high stability in air even for four months. The high air stability of these magnetite could be due to the surfactant capped on the particle surface. This method of synthesis has some advantages including simplicity, high product quality, and acceptable reproducibility. Therefore, the magnetite particles can be used for different applications such as in catalysis and drug delivery.

单相可控单分散磁铁矿Fe3O4纳米粒子的合成

我们报道了一种简单的溶剂热方法，该方法用于从可得且便宜的单一铁前驱体（FeCl ₃）以及作为共封端剂的醋酸钠和乙二胺合成单分散磁铁矿纳米颗粒，其粒径控制在40至200 nm 。通过合成的反应时间可以容易地控制粒径。透射电子显微镜，x射线衍射，傅立叶变换红外光谱和x射线光电子光谱技术用于研究获得的颗粒。结果表明，所得的氧化铁颗粒表现出单一磁铁矿Fe ₃ O _4。即使在空气中四个月也能保持稳定的相位。这些磁铁矿的高空气稳定性可能是由于表面活性剂覆盖在颗粒表面上。这种合成方法具有一些优点，包括简单，高产品质量和可接受的可重复性。因此，磁铁矿颗粒可用于不同的应用，例如在催化和药物递送中。
