| Nanometer MnO2: Hydrothermal Synthesis and Effect of Salt Modifiers on Polymorph & Morphology |
|
| 摘要: 在水热条件下，向反应体系中加入简单的无机盐，利用KMnO4和MnCl2反应生成不同晶型/形貌的一维MnO2纳米材料。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)等对产物进行了结构和形貌的表征。结果显示，加入的简单无机盐不仅影响产物的晶型，同时也对产物的形貌也起到了控制作用。 |

| Abstract: Nanometer MnO2 materials with different polymorphs & morphologies were prepared under hydrothermal conditions by reacting of KMnO4 and MnCl2 with various salts. 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 both of the polymorph and the morphology are affected by the salt modifiers. |
