Abstract: Transition metal oxides (WO3, MoO3, V2O5) are intensively studied for applications in batteries, catalysis and energy storage. There are several methods for thin films preparation of these materials, including electrodeposition from aqueous electrolyte solutions. In this paper it is studied the electrochemical deposition of molybdenum oxides at different electrodeposition potentials using peroxo-polymolybdate and ammonium molybdate as precursors in a 0.05 M solutions at pH = 2.3 and 5.5. Metallic copper was used as a support. The obtained thin films have been characterized by cyclic voltammetry, optical microscopy and differential scanning calorimetry. Keywords: electrodeposition, thin film, cyclic voltammetry. |
