Preparation and Characterization of Pt/YSZ Electrode of Zirconia Oxygen Sensor

Abstract:

Electrode slurry made of Pt powder was brushed on both surfaces of the sintered ZrO2 substrate. And then the Pt electrodes were sintered under various temperatures. The microstructure of the surface of the electrodes was characterized by scanning electronic microscope. The electrochemical properties of the electrodes were investigated by electrochemical impedance spectroscopy (EIS). The results show that the sintered temperature of the electrode has a remarkable effect on the microstructure of the electrode and the Pt electrode show favorable electrochemical catalysis performance.
