In situ monitoring of the rising of aqueous solution meniscus for a partially immersed silver electrode during electrochemical reduction of oxygen

Rising phenomena of aqueous solution meniscus were found for the silver electrode of a 5 MHz piezoelectric quartz crystal (PQC) partially immersed in Na2SO4, NaClO4, HClO4 and NaF aqueous solutions at oxygen reduction potentials, respectively. A detailed study revealed that a decrease in contact-angle hysteresis (or a contact-angle decrease) and a continued collection of the water product at the solid-gas-solution interface during oxygen reduction, rather than the electrocapillary effect and an agitation effect induced by the oscillation of PQC, are responsible for the meniscus-rising phenomena. In addition, in situ determination of the immersed height of a partially immersed Ag electrode was studied on the basis of simultaneous measurements of the electroacoustic admittance and electrochemical impedance.
