Abstract

The iridium/iridium oxide pH sensors were fabricated by thermal oxidation, during which one, two and three times of quenching were performed in deionized water, respectively. The characteristics and properties of the sensors developed with different quenching times were examined extensively, which include surface morphology, section structure, porosity distribution, as well as the linear range of E-pH response, pH response rate, and the long time stability, etc. It is found that the sensors quenched for three times appear to show better performance. Electrochemical impedance spectra (EIS) of the iridium oxide electrodes were investigated in pH buffer to analyze the pH response mechanism of the electrode.
