摘　　要：多壳层中空介孔结构由于比表面积大、结构稳定性好、离子传输路径短等优点被广泛应用于各类高性能电极材料,然而双金属氢氧化物多孔多壳结构在结构稳定性和电导率方面仍存在研究上的不足。通过MnSn(OH)_(6)化学反应的自生长以及在碱性介质中的动态刻蚀,合成了尺寸均匀的MnSn(OH)_(6)介孔单晶纳米结构,又通过静电组装在纳米立方体外层包覆了聚吡咯(PPy),得到了MnSn(OH)_(6)超级电容器电极材料,进一步提升导电性能。其在1 A/g的电流密度下的比电容为569.6 F/g,具有较高的比电容和较好的循环倍率性能。Due to large specific surface area, good structural stability, short ion transport path and other advantages, multi-shell hollow mesoporous structure has been widely used in various high-performance electrode materials. However, there are still deficiencies in the study of the structural stability and conductivity of bimetallic hydroxide porous multi-shell structure. MnSn(OH)_(6)mesoporous single crystal nanostructures with uniform size were synthesized through the self-growth of MnSn(OH)_(6)chemical reaction and dynamic etching in alkaline medium. And to further improve the conductivity, the electrode material of MnSn(OH)_(6)supercapacitor was obtained after polypyrrole(PPy) being coated in the outer layer of the nanocube by electrostatic assembly. Its specific capacitance is 569.6 F/g at a current density of 1 A/g, which has higher specific capacitance and better circulation ratio performance.
