Micro/nanostructured materials have attracted a great deal of attention, and many strategies have been developed to fabricate micro/nanostructured materials.
Amine-functionalized micro/nanostructured FeO with different sizes was synthesized conveniently in organic media. The chemical structures of as-synthesized products were characterized by FTIR, TEM, SEM, and XRD.
The ligand binds to the FeO core by hydrogen bond between the oxygen atom on the surface of FeO and the hydrogen atom in molecular ethylenediamine. Their magnetic properties were also investigated.
First, there is no need to control the reaction under a nitrogen atmosphere, and just one salt is used as an iron source. The growth and the surface modification of FeO crystalline nucleation happen at the same time. Second, monodispersed FeO micro/nanospheres were prepared without additional surfactant or external magnetic fields. Third, this method is preferred compared with the conventional organic phase method, as the reaction condition is milder and less pollutant will be produced.
微纳结构材料已引起广泛关注，人们已开发出多种制备微纳结构材料的策略。
在有机介质中简便地合成了不同尺寸的胺官能化微纳结构FeO。通过傅里叶变换红外光谱（FTIR）、透射电子显微镜（TEM）、扫描电子显微镜（SEM）和X射线衍射（XRD）对合成产物的化学结构进行了表征。
配体通过FeO表面的氧原子与分子乙二胺中的氢原子之间的氢键与FeO核结合。还研究了它们的磁性。
第一，无需在氮气气氛下控制反应，仅使用一种盐作为铁源。FeO晶核的生长和表面改性同时发生。第二，无需额外的表面活性剂或外部磁场即可制备单分散的FeO微纳球。第三，与传统有机相法相比，该方法更具优势，因为反应条件更温和，产生的污染物更少。
