Study of zinc hexacyanoferrate-modified platinum electrodes using electrochemical quartz crystal microbalance

Abstract

In this work, the electrochemical quartz crystal microbalance has been employed to monitor directly the in situ growth of the zinc hexacyanoferrate film during the electrodeposition. Mass changes of the platinum|crystal working electrode were correlated with cyclic voltammetry data. Effects of the sorption of counter-cations (K(+), Na(+), and ) during redox reactions were studied. The electrocatalytic oxidation properties of procaine by the zinc hexacyanoferrate films were performed.
