The structural and electrochemical properties of lanthanum manganate (LaMnO3) powder prepared by the sol-gel method are researched in this article. The powder calcined at 600 °C showed amorphous, and the powder calcined at 700-800 °C showed the pure phase of the LaMnO3. The grains with the size of about 80-120 nm were agglomerating together. Cyclic voltammetry and galvanostatic charge-discharge were used to characterize the electrochemical properties in alkaline environment. The electrochemical properties calcined at 700 °C showed a specific capacitance of 73 F/g at the current density of 0.5 A/g. The raw materials for preparing the LaMnO3 powder are cheap, and the operation method is simple.

Kinetics Of

The electroreduction of Zn2+ was studied in propylene carbonate (PC), acetonitrile (ACN), and hexamethylphosphoramide (HMPA) on mercury at various concentrations of tetraethylammonium perchlorate as a supporting electrolyte using dc polarography, cyclic voltammetry, chronoamperometry, and ac polarography. It was found that in PC and ACN the electroreduction process proceeds in one step. In HMPA, however, the electroreduction proceeds through a CEE mechanism in which a chemical reaction is followed by a charge transfer in two steps. The heterogeneous rate constants, corrected for the double layer effects, decrease with increase in the solvent donor number. The electroreduction process proceeds through the cation transfer mechanism.

Hydrothermal Approach

The α-MnO2 spherical assemblies were prepared via a facile hydrothermal approach in the presence of sodium dodecyl sulfate (SDS). The assembled nanostructures were composed of the MnO2 nanorods with 150–200 nm in width and several micrometers in length. The products were characterized by SEM, TEM and XRD. The electrochemical characterization was carried out by cyclic voltammetry, which indicated that the α-MnO2 spherical assemblies were of an excellent electrode material for supercapacitor.
