Ion Transfer at Nanointerfaces between Water and Neat Organic Solvents

摘要

The need for electrolyte to be present in both liquid phases is a major constraint in electrochemistry at the interface between two immiscible electrolyte solutions (ITIES).By narrowing the polarization window,supporting electrolyte prevents one from studying ion transfer (IT) and electron-transfer reactions occurring at high positive (or negative) interfacial voltages.A number of other problems (e.g.,impurities,interfacial precipitation,adsorption,and ion paring) associated with the presence of electrolyte often impair electrochemical studies at the ITIES.
