| 摘 要： | 在C4H6MnO4.H2O水溶液中,采用电化学沉积法制备了Mn3O4电极,研究了所制电极的微观结构及性能。结果表明,当电沉积液中添加有NaNO3时,所制Mn3O4电极具有纳米级薄片所构成的多孔表面,且性能优异,其电化学传递阻抗小,比容达到122.5 F.g–1,比未添加NaNO3时提高了70%。

| Abstract: | Mn3O4 electrodes were prepared by electrochemical deposition in the C4H6MnO4·H2O aqueous solution.The microstructure and properties of the Mn3O4 electrodes were studied.The results show that the Mn3O4 electrodes prepared in the C4H6MnO4·H2O solution with NaNO3 show a porous surface consisting of nano-sheets and exhibit good performance: their charge transfer resistance is low,while their specific capacitance reaches 122.5 F·g-1,which is 70% higher compared with the electrodes prepared without NaNO3. |
