Morphology-controllable synthesis of MnO2 hollow nanospheres and their supercapacitive performance
Original language description
Uniform MnO2 hollow nanospheres with hierarchical (urchin-like and flower-like) and non-hierarchical structures have been synthesized via a dual-template assisted hydrothermal process. The morphology control of the MnO2 hollow spheres can be easily achieved by altering the mass ratio of Pluronic F-127 to silica spheres. Material characterizations reveal that urchin-like hollow spheres possess the highest BET surface area of 233.4 m 2 g-1 among the diverse morphologies. A possible formation mechanism forthe MnO2 hollow spheres with different morphologies is proposed. The supercapacitive performance of the MnO2 spheres was investigated by cyclic voltammetry and galvanostatic charge-discharge techniques. The urchin-like hollow spheres exhibit the highestspecific capacitance of 266.6 F g-1 within the potential range of 0-1.0 V. The relationship between the specific capacitance and the morphology of the MnO2 hollow spheres is also discussed. The good capacitive behavior and cycling stabil
