A facile process was developed to synthesize MoS2 nanospheres by a simple PVP assisted hydrothermal method. The samples were characterized by XRD, SEM and Electrochemical tests. SEM demonstrates that the obtained MoS2 has sphere-like morphology in the presence of surfactant PVP. Electrochemical measurements show that the initial discharge capacity of the MoS2 nanospheres is 1915.1, 895.8 and 761.6 mAh g-1 at current densities of 100, 400 and 800 mA g-1, respectively. Meanwhile, it is found that the MoS2 nanospheres have improved rate capacity and cycle stability.

First Time

The microwave-hydrothermal method for synthesizing g-MnO2 has been investigated for the first time. The dandelion-like g-MnO2 active material with 1.0-5.0 μm in diameter was obtained from KBrO3 and MnSO4 via the novel method. Compared with traditional low-temperature hydrothermal method, this approach lowers the temperature by 30-40 °C, and shorts the reaction time 6-14 h. Electrochemical properties of dandelion-like γ-MnO2were elucidated by cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy tests. The synthesized material shows a relative high specific capacitance, and the MnO2 obtained at the condition of 75 °C for 2 h shows the best electrochemical properties with a specific capacitance of 239.3 F·g-1 at the current density of 100 mA·g-1 in 6 M KOH electrolyte solution.
