Anomalous hysteresis and current fluctuations in cyclic voltammograms at microelectrodes due to Ag leaching from Ag/AgCl reference electrodes
We observe anomalous cyclic voltammograms (CVs) measured with microelectrodes immersed in a Fe(CN)63−/4− redox buffer, which exhibit pronounced hysteresis, current fluctuations, a current level that increases with successive scans, and current suppression at positive potentials in the anodic scan.
