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。
Mn3O4 polyhedral nanocrystals were prepared by a simple water-based pyrolysis of un-added manganese acetate-ethanol system. The effect of Mn3O4 (superscript 3 +) on the photocatalytic activity of Mn3O4 by XRD, SEM, TEM, FTIR, Raman spectroscopy and X - ray photoelectron spectroscopy (XPS) The structure and morphology were characterized. The formation mechanism of Mn3O4 polyhedron nanocrystals was proposed. Cyclic voltammetry (CV) test results show that the prepared Mn3O4 electrode exhibits good pseudocapacitance. At a scan rate of 5 mV.s-1, the maximum specific capacitance of Mn3O4 was 173 F.g-1.
