摘　　要：利用含锰的POMOFs({SiW10Mn2}@Mn-MOF)材料为模板,在氮气保护下进行煅烧得到了MnO@WO3@C复合材料,采用IR、XRD、SEM、XPS对合成得到的化合物进行了结构表征,并以此作为超级电容器电极材料进行测试,结果表明MnO@WO3@C在电流密度为1 A·g^-1时比电容为120.5 F·g^-1,5000次循环后显示了93.3%的电容保持率,体现了材料优异的电化学稳定性.In this paper,MnO@WO3@C composite was prepared by calcining{SiW10Mn2}@Mn-MOF in nitrogen atmosphere.The composition and structure of the synthesized materials were characterized by IR、XRD,SEM and XPS.The supercapacitivee performance was tested by using it as electrode active material.The results showed that:MnO@WO3@C shows 120.5 F·g^-1 when the current density from 1 A·g^-1.After 5000 cycles,the capacity retention rate is 93.3%.
