摘要: 在微酸性环境中高锰酸钾自身分解,利用低温水热法制备了花状形貌的Birnessite型层状氧化锰。探讨了温度及表面活性剂对其形貌的影响。采用XRD、 SEM、 N2吸附-脱附实验等手段对所合成的多孔材料进行了表征。花状形貌的层状氧化锰在 1 mol/L 的硫酸钠溶液中,扫描速度为 5 mV/s 时显示出较高的比电容,其比电容达到 190 F/g。

关键词: 层状氧化锰, 花状, KMnO4, 比电容

Abstract: Birnessite type layered manganese oxide with flower-like morphology was synthesized via low-temperature hydrothermal treatment in weak acidic KMnO4 solution.Effects of temperature and surfactants on the morphology and structure of the product were investigated.The as-prepared material was characterized by XRD,SEM,and N2 adsorption-desorption.Specific capacitance of layered manganese oxide with flower-like morphology reached as high as 190 F/g at a sweep rate of 5 mV/s in 1 mol/L Na2SO4 solution.

Key words: layered manganese oxide, flower-like, KMnO4, specific capacitance
