| 摘要: 本文介绍了以大环多胺(六甲基-1，4，8，11-四氮环14-4，11-二烯)的镍(Ⅱ)配合物溶液为反应物，水热水解制备出花状β- Ni(OH)2亚微米结构，该花状β-Ni(OH)2由几十个相互连接的纳米片构成。对中间产物的研究结果表明，随着配合物浓度的增加、反应时间的延长，产物形貌从卷曲的片状转变成纳米片组成的花状且花状结构逐渐增密。采用粉末X-射线衍射(XRD)、透射电子显微镜(TEM)和场发射扫描电子显微镜(FESEM)表征了产物，并采用Rietveld精修方法拟合了晶体结构。 | |

| Abstract: β-Ni(OH)2 flower-like submicroscaled patterns composed of dozens of nanoflakes were successfully synthesized by hydrothermal hydrolysis of the nickel(Ⅱ) complex solution of macrocycle polyamine (hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene). Investigation on the intermediates shows that the shape of products changes from curled nanoflakes to flower-like patterns then dense flower-like patterns with the increase of complex concentration and reaction time. The product was characterized by XRD, TEM and FESEM and the crystal structure was simulated with Rietveld Refined Method. | |
