摘要
以FeC l2.4H2O和FeC l3.6H2O为原料,采用水热法合成了Fe3O4磁性纳米微粒.考察了不同氧化还原剂,螯合剂和表面活性剂等因素对产物形貌和尺寸的影响,运用透射电镜(TEM)、红外光谱(FTIR)和X-射线衍射(XRD)对其微结构进行了表征,还用振动样品磁强计(VSM)对样品的基本磁性能进行了表征.
Magnetic Fe3O4 nanoparticles was synthesized via the hydrothermal method by using FeCl·4H2O and FeCl3·6H2O as raw materials. The effects of various kinds of oxidants or reductants, surfactants and chelates on the size and morphology of the product were examined, and the microstructure were investigated by transmission electron microscopy （ TEM ）, Fourier Transform Infrared （FTIR） and X - ray diffraction （XRD）. Preliminary magnetic properties of the nanoparticles were characterized by using a vibrating sample magnetometer （VSM）.
