通过十二烷基硫酸钠（SDS）辅助水热处理方法制备了具有海胆形状的MnO2纳米结构。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、能谱仪(EDS)和X射线衍射(XRD)对产物进行了表征。 XRD图谱表明海胆状MnO2纳米结构为四方相。此外，SEM 和 TEM 显示海胆形状的 MnO2 纳米结构由 150−200 nm 宽、几微米长的 MnO2 纳米棒组成。提出并详细解释了海胆形状的 MnO2 纳米结构的生长机制。
MnO2 nanostructures with sea urchin shapes have been prepared by an sodium dodecyl sulfate (SDS)-assisted hydrothermal treatment method. The products were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). XRD patterns indicated that the sea urchin shaped MnO2 nanostructures were tetragonal phase. Furthermore, SEM and TEM revealed that MnO2 nanostructures with sea urchin shapes consisted of MnO2 nanorods 150−200 nm wide and several micrometers long. A growth mechanism of MnO2 nanostructures with sea urchin shapes was suggested and explained in detail.
