摘要

This work describes the use of interdigitated array electrodes (IDAE) for proton detection. Methanol electrooxidation in sulfuric acid solution was exemplified. Reduction currents originating in the reaction product generated by methanol electrooxidation on a Pt generator electrode were observed at the Pt collector electrode, the potential of which was fixed in the hydrogen evolution region. In order to reduce the background current of hydrogen evolution, an Hg-plated Pt collector electrode was fabricated. Compared to the Pt collector electrode, the reduction current observed at the Hg collector electrode was extremely small. The product detected was found to be a proton from the current responses observed at Pt and Hg collector electrodes. [References: 28]
