A supercritical fluid technique was used to prepare hexagonal nanoplatelets of magnetite. Ferrocene was used as the Fe source, and sc-CO(2) acted as both a solvent and oxygen source in the process. Powder X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and magnetic measurements were used to characterize the products. It was found that the morphology and structure of the product strongly depended on the reaction conditions.
采用超临界流体技术制备了六方纳米片状磁铁矿。二茂铁作为铁源，sc-CO2 在反应中既作为溶剂又作为氧源。采用粉末 X 射线衍射、透射电子显微镜、X 射线光电子能谱和磁测量对产物进行了表征。结果发现，产物的形貌和结构强烈依赖于反应条件。
