Fabrication of Hybridized Microparticles Composed of Mesoporous Manganese Dioxide and Fullerene C₆₀ Nanocrystals

Preparation of Hierarchic Porous Films of α-MnO2 Nanoparticles by Using the Breath Figure Technique and Application for Hybrid Capacitor Electrodes

“…In our previous study, the surface of MnO 2 particles was decollated with fullerene nanocrystals. 16 Capacitors made from such composites exhibited higher capacitance than those of original MnO 2 . The added fullerene nanocrystals contributed to both improving the conductivity and increasing double layer capacitance.…”

“…Some general drawbacks of MnO 2 are the low surface area as it tends to form large crystals and low conductivity, both limiting the performance of the capacitor. , Application of MnO 2 is therefore hindered due to small Coulombic capacity in its practical use and large energy loss on charging/discharging at high rates. , In order to improve the device performance of MnO 2 supercapacitors, we have focused on both improving the electrical conductivities and increasing the surface area of electrodes by introducing hierarchically porous surface structures. In our previous study, the surface of MnO 2 particles was decollated with fullerene nanocrystals . Capacitors made from such composites exhibited higher capacitance than those of original MnO 2 .…”
