Abstract

We report a new fabrication method to produce palladium hydride pH microelectrode using a chemical approach to synthesize the palladium hydride. In contrast to electrochemically generated palladium hydride microelectrodes, chemically generated palladium hydride microelectrodes are longer lasting and importantly have a good analytical performance under aerobic conditions. Chemically generated palladium hydride microelectrodes perform best in acid to neutral electrolytes devoid of Cl⁻. They can readily be produced on 10 μm diameter disk platinum microelectrodes, which makes them attractive candidates for future localized electrochemical studies.
