Capacitance of MnO2 Micro-Flowers Decorated CNFs in Alkaline Electrolyte and Its Bi-Functional Electrocatalytic Activity toward Hydrazine Oxidation |
| 초록 |
The specific capacitances of nanostructure at different scan rates are shown. The specific capacitance decreases with the increase of scan rates from 5 to 75 mVs−1. At low scan rates (5 mVs−1), both active areas ( internal and external) of the surfaces of electrodes could take part in reaction while at high scan rate (75 mVs−1) the diffusion of the electrolyte ions was limited thus only the external surface area of electrodes could participate in ion transfer reaction. As shown in fig.1 (b) the maximum specific capacitance obtained at a scan rate of 5 mVs−1 of was 120 Fg−1. The CV curve indicates an excellent electrocatalytic activity of nanostructure by showing effective hydrazine oxidation with high current density in presence of hydrazine (Red). At the potential of 1 V, the current density of the nanostructure reached 38 mA cm−2, which was about double than that in 1 M KOH . |
