纳米MnO2的液相法制备及电化学性能研究
Synthesis and electrochemical properties of nanostructure manganese dioxide by fluid phase method
摘要
Abstract
In this paper, using MnSO4·H2O and K2S2O8 as reactants, MnO2was synthesized by fluid phase method. The products were characterized by XRD, FTIR and SEM, the electrochemical properties of the materials were investigated by cyclic voltammetry, impedance and current charge/discharge measurements. The results show that under the condition pH=1.0, 0=60 ℃ and t =22 h, the pure nanostructure α-MnO2 of system can be synthesized. In cyclic voltammetric tests, the results show that manganese dioxide in smaller scanning speed conditions have better capacitance performance. The constant current charging and discharging experiments show that the manganese dioxide has good capacitance characteristics.关键词
