| 摘要: 通过对未加添加剂的醋酸锰-乙醇体系的一种简易的水基热解过程，制备了Mn3O4多面体纳米晶体。借助X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱法(FTIR)、拉曼光谱和X-射线光电子能谱(XPS)等对Mn3O4的结构和形貌进行了表征。提出了Mn3O4多面体纳米晶体的形成机理。循环伏安法(CV)测试结果表明，所制得的Mn3O4电极呈现良好的赝电容性能。在扫描速率为5 mV·s-1时，得到了Mn3O4的最大比电容值173 F·g-1。 |

| Abstract: Hausmannite Mn3O4 polyhedral nanocrystals have been fabricated through a simple solution-based thermolysis process in the manganese acetate-alcohol system. Structural and morphological characterizations of the as-obtained product have been carried out using XRD, FTIR, Raman spectraoscopy, XPS, SEM and TEM. The formation mechanism of polyhedral nanocrystals was proposed. The cyclic voltammetry (CV) result show that the as prepared Mn3O4 electrode exhibits a good pseudo-capacitance behavior. A maximum specic capacitance of 173 F·g-1 is obtained for the nanocrystals at a sweep rate of 5 mV·s-1. |
