| 摘 要： | Simultaneous and fast measurement of the piezoelectric quartz crystal (PQC) impedanceduring electrochemical pertUrbations, i.e., the electrochemical quartz crystal impedancesystem (EQCIS) called by us, characterizes the PQC resonance better by providingmultidimensional in sl'tu piezoelectric information than the conventional electrochemicalquartz crystal microbalance (EQCM)'-'. The PQC impedance has been analyzed basedon the Butterworth-Van Dyke (BVD) equivalent electrical circuit com…

| Abstract: | The electrochemical quartz crystal impedance system (EQCIS) has been used for the study of a partially immersed An electrode in 0.2 mol/L NaCIO_4. aqueous solution. The influences of the immersed area and height of the electrode on the EQCIS responses were evaluated, showing the highest response sensitivity to liquid loading at the center of the piezoelectric quartz crystal electrode. The increase in the immersed height of the An electrode at oxygen reduction potentials during potential cycling was measured by this technique. |
