Electrochemical Behaviour for Europium Doped Tantalum Oxide Coated Glass Carbon Electrode

Abstract:

Europium doped tantalum oxide (europium-Ta₂O₅) particles were synthesized with a low temperature hydrothermal method. The electrochemical behaviour of an europium-Ta2O5 film electrode in 0.1 mol dm^-3 KCl solution containing 5 mmol dm^-3 K₃Fe(CN)₆ was investigated using cyclic voltgrammetry (CV). The CV results indicated that the europium-Ta₂O₅ film electrode exhibited good stable and reversible electrochemistry properties. The electrochemical reaction of K₃Fe(CN)₆ was a diffusion-controlling process on the europium-Ta₂O₅ film electrode. The europium-Ta₂O₅ particles might have potential applications in electrochemical fields.
