中文摘要：

以DBS（十二烷基磺酸钠）为形态控制试剂，在水-丁醇体系中成功合成了准立方体形貌的α-Fe2O3纳米颗粒。通过扫描电子电镜（SEM）、X-射线衍射仪（XRD）、透射电子电镜（TEM）、紫外分析光谱（UV—vis）以及振动样品磁强计（VSM）等手段等对产物进行了表征。研究表明，体系中DBS含量对α-Fe2O3的生成和形貌有着重要的影响，在DBS含量较少时主要得到α-FeOOH纳米棒，而随着DBS含量增大得到α-Fe2O3纳米准立方体，获得的准立方α-Fe2O3纳米颗粒有着优异的室温磁性能。

英文摘要：

Quasi -cubic α-Fe2O3 nanoparticles were prepared in water- butanol system by hydrothermal method using sodium dodecylbenzene sulfonate （DBS） as controller. X - ray power diffraction （ XRD）, Scanning electronmicroscope （ SEM）, Transmission electron microscope （ TEM）, Ultraviolet visible spectrophotometer （ UV - vis） and vibrating sample magnetrometer（VSM） were employed to study the crystal structure, morphology, optical and magnetic properties of the as - obtained products. Results showed that DBS played a vital role in the formation of α-Fe2O3 nanocubes, when the amount of DBS is lower, the α-FeOOH nanorods were obtained; with the increase amount of DBS, α-Fe2O3 nanocubes were obtained, the as -prepared α-Fe2O3nanoparticles had excellent magnetic properties.
