将氧化铁纳米颗粒负载到通过在含氟电解质中阳极氧化Ti生长的自组织TiO 2纳米管层上。室温下，在甘油/水/FeCl 3中心点6 H（2）O电解液中，采用电沉积法制备了纳米粒子。X射线衍射（XRD）、高分辨透射电子显微镜（HRTEM）和X射线光电子能谱（XPS）测试表明，纳米粒子由纳米铁（Fe）和磁铁矿（Fe 3 O 4）组成。通过在空气中在450 ℃下退火获得赤铁矿（α-Fe 2 O3）结构。并对纳米粒子的生长机理和形貌进行了描述。此外，纳米粒子在室温下表现出良好的铁磁性能。(C)2010爱思唯尔有限公司保留所有权利。
The iron oxide nanoparticles were loaded onto self-organized TiO2 nanotube layers grown by anodization of Ti in fluoride containing electrolytes. The nanoparticles were obtained by electrodepositing method in glycerol/water/FeCl3 center dot 6H(2)O electrolytes at room temperature. The X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) measurements showed that the nanoparticles consisted of iron nanocrystalline (Fe) and magnetite (Fe3O4). The hematite (alpha-Fe2O3) structure was obtained by annealing in air at 450 degrees C. The growth mechanism of the nanoparticles and their morphology were also described. Furthermore, the nanoparticles exhibited good ferromagnetic properties at room temperature. (C) 2010 Elsevier Ltd. All rights reserved.
