- Electrodeposited mixed nanostructures composed of conducting polyaniline (PANI) and hydrous
ruthenium oxide (H-RuO2) referred as a hybrid nanostructure was synthesized. The surface morphology
was investigated from the field-emission scanning electron microscopy digital photoimages. Fibrous
network of PANI and spheres of H-RuO2 were obtained. PANI embedded H-RuO2 was confirmed from the
Raman spectroscopy analysis. Cyclic-voltammetry, used to characterize the electrochemical capacitive
properties of hybrid PANI/H-RuO2 (RP 30) nanostructure, showed a specific capacitance as high as 322 F/
g in 0.5 M H2SO4 electrolyte. The electrochemical impedance spectroscopy measurement revealed the
low equivalent series resistance.
