Electrocatalytic Property of Potassium Tantalate Film Coated Electrode

Abstract:

In this work, potassium tantalate (KTaO₃) particles were synthesized using a low-temperature hydrothermal method. The phase structure of samples prepared was performed by X-ray diffraction (XRD). The result revealed that it belongs to cubic crystal. The electrochemical behaviour of a KTaO₃ film coated electrode was investigated in 0.1 mol dm^-3 KCl containing 5 mmol dm^-3 K₃Fe (CN)₆ with cyclic voltgrammetry (CV). The CV results indicated that the KTaO₃ film coated electrode exhibited excellent electrochemical stability. The electrochemical reaction of K₃Fe (CN)₆ on the KTaO₃ film coated electrode was a diffusion-controlling process.
