- W2364474477 abstract "Mesoporous MnO2 for supercapacitors was prepared by using Na2S2O3 as the reducing agents and KMnO4 as the oxidant.The samples were analyzed by scanning electron microscope(SEM),N2 adsorption-desorption and X-ray diffraction(XRD).Cyclic voltammetry and galvanostatic charge/discharge were used to characterize the electrochemical performance.The results showed that the as prepared nanomaterial was amorphous MnO2 with a diameter of 20-40nm.The specific surface area and mean pore diameter was 182.6m2/g and 6.2nm,respectively.In an electrolyte of 1mol/L(NH4)2SO4,the MnO2 had typical capacitive characterization and high power in the potential region of-0.4-0.5V(vs SCE).At a current density of 10mA/cm2,a specific capacitance of 397F/g was achieved.The Mesoporous MnO2 exhibited high cycling efficiency." @default.
