Ion transfer processes at 4-(3-phenylpropyl)-pyridine | aqueous electrolyte | electrode triple phase boundary systems supported by graphite and by mesoporous TiO2
Abstract
Biphasic electrode systems allow electrochemical reactions to be driven in a microphase of organic liquid (typically 1–100 nL), which is coupled via ion transfer processes to the surrounding aqueous electrolyte medium. Microdroplet deposits on basal plane pyrolytic graphite as well as thin film deposits of the organic phase within a mesoporous titanium oxide host film are investigated.
