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.
