| 摘 要： | 在无模板和表面活性剂的水热条件下,调节反应参数,可以得到一致的片状六方相β-Co(OH)2和多层片状的β-Co(OH)2微/纳米材料.合适的反应条件下,可以制备一致的结晶性好的单片状六方相β-Co(OH)2.用X射线衍射(XRD)、场发射扫描电镜(FESEM)、透射电镜(TEM)、高分辨透射电镜(HRTEM)以及选区电子衍射(SAED)等对反应产物进行了结构和形貌的表征.结果显示,Co(NO3)2的起始浓度、反应温度及溶液成分(异丙醇的加入)对反应产物的形貌结构有着重要的影响.

| Abstract: | The hexagonal single-platelike or muti-platelikeβ-Co（OH） 2 have been successfully synthesized by changing the reaction condition through a simple surfactant-free and hydrothermal method.Under a suitable reaction condition,the perfect single-layer hexagonalβ-Co（OH） 2 platelets with highly crystalline nature can be obtained.The structure and morphology of the resultant products were characterized by using XRD,FESEM,TEM,HRTEM and Selected-Area Electron Diffraction（SAED） .The results show that the morphology and structure of the obtained products can be strongly influenced by changing the reaction condition,such as：Co（NO3） 2 concentrations,reaction temperature and composition of solutions（addition of isopropyl alcohol） . |
