Electrochemical Property of Terbium Doped Tantalum Oxide Film Electrode

Abstract:

Terbium doped tantalum oxide (Tb-Ta₂O₅) particles were synthesized with a low hydrothermal method. The phase structure of Tb-Ta₂O₅ obtained was performed by X-ray diffraction (XRD). The result revealed that the terbium doped Ta₂O₅ belongs to orthorhombic crystal. The electrochemical property of methylene blue (MB) at Tb-Ta₂O₅ film electrode in 0.5 mol dm^-3 KCl aqueous solution was investigated with cyclic voltgrammetry (CV). The CV result indicated that the electrochemical kinetics of MB was diffusion controlling at Tb-Ta₂O₅ film electrode. Tb dopping imporved the electrochemical property of Ta₂O₅ film electrode. Tb-Ta₂O₅ is used as a kind of electrode material which has some new potential applications.
