Electrochemistry at liquid-liquid interfaces has emerged in recent times into the area of chemistry that needs understanding and controlling interfacial charge transfer reactions. The interface is usually formed between liquid and an organic solvent phase, both constituting dissolved electrolyte salts, but the interface between water and an ionic liquid or between an organic solvent and an ionic liquid can also be formed. Charge transfer reactions at these interfaces are very crucial, in sensing and detection; in separation processes, both analytical and preparative; and in energy-harvesting devices and mechanisms.
When two homogeneous bulk phases meet there is a point of particular thickness where the properties are changed and that region is called interface. At the molecular level, the level of thickness of the interfacial region is not zero, but is significant. The properties of interfacial region can be important for colloidal systems, usually for dispersions, where the surface:volume ratio is not negligible. Electrochemistry at liquid to liquid interface is concerned with three types of charge-transfer reactions, ion-transfer reactions from one phase to another, ion-transfer reactions assisted by the presence of a complexing agent, and Electron transfer reaction between hydrophilic and hydrophobic redox couple. A journal is a periodic publication intended to further progress of science, usually by reporting naive research and innovations.
