Anisotropic growth of magnetite (Fe3O4) nanoparticles is achieved in a hydrothermal growth process using hexamine to play a dual role of oxide forming and directing agent. The samples are characterized by X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy, squid magnetometry, ferromagnetic resonance technique, diffuse reflectance spectroscopy and Mössbauer spectroscopy, which collectively establish the formation of Fe3O4 phase. Anisotropic structures such as nanorods and nanotubules are revealed and these are shown to exhibit good humidity sensing properties.
在水热生长过程中，使用六亚甲基四胺作为氧化物形成剂和导向剂，实现了磁铁矿（Fe3O4）纳米颗粒的各向异性生长。通过X射线衍射、扫描电子显微镜、高分辨率透射电子显微镜、超导量子干涉仪磁力测量、铁磁共振技术、漫反射光谱和穆斯堡尔光谱对样品进行了表征，这些表征共同证实了Fe3O4相的形成。揭示了纳米棒和纳米管等各向异性结构，并且这些结构显示出良好的湿度传感特性。
