新型纳米结构二氧化锰的制备及其超级电容性能
Preparation and supercapacitive performance of a novel nanostructural MnO2
摘要
Abstract
Cauliflower MnO2 was prepared by hydrothermal synthesis method by reacting MnSO4 and (NH4)2S2O8 with Fe(NO3)3. The samples were analyzed by X-ray diffraction(XRD) and scanning electron microscopy (SEM). Cyclic voltammetry and galvanostatic charge-discharge were used to characterize the electrochemical performance of the samples. The results show that the prepared samples are α-MnO2. The particles are in a caulillower shape. In an electrolyte of 6 mol/L KOH , electrode based on the MnO2 show perfect supercapacitor characterization in the potential region of 0～0.4 V. At a current density of 100 mA/g , a specific capacitance of 176 F/g is achieved.关键词
