摘要(Abstract)：

以Mn Cl_2、KMn O_4和Na OH为反应物原料,采用液相氧化还原法制备得到层状二氧化锰中间体,然后以层状二氧化锰和Na OH为原料,采用水热法制备了OMS-5型(八面体分子筛)纳米Mn O_2电极材料。分别用X射线衍射光谱、扫描电镜和傅里叶-红外光谱等表征样品的晶体结构、形貌和键合特性;采用循环伏安、恒流充放电和交流阻抗等方法研究其电化学性能。结果表明:OMS-5型纳米Mn O_2结晶良好,直径约为50 nm;在0.5 mol/L的Li_2SO_4和Na_2SO_4电解液中,电流密度为0.1 A/g时,其比电容分别为47.4、170.3 F/g;等效串联电阻和漏电流小,在Na_2SO_4电解液中展现出良好的循环稳定性,表明该OMS-5型纳米Mn O_2是一种可能具有应用前景的超级电容器电极材料。
