Title: Scanning electrochemical microscopy study of ion transfer process across interface supported by hydrophobic carbon ceramic electrode
Abstract: A carbon ceramic electrode (CCE) modified with the redox solution in hydrophobic organic ether and immersed into an aqueous solution studied by scanning electrochemical microscopy (SECM). After the oxidation of decamethylferrocene, its cations were near the electrode surface in the aqueous phase. This indicates some fraction of the redox-active cations electrochemically in the organic phase is transferred across the liquid/liquid They are reduced at the SECM tip and form a solid deposit. amount of deposited decamethylferrocene was estimated by the anodic at the tip. It is affected by the substrate-tip distance, time, and electrolyte concentration. The SECM images of and modified CCEs are consistent with their heterogeneous structure.
