Electrocatalysis at the polarised interface between two immiscible electrolyte solutions

Electrocatalysis at the interface between two immiscible electrolyte solutions (ITIES) is an emerging field of research, which allows separation reactants according to their lipophilicity. Electrocatalysts various natures (noble metals, carbon-based and inorganic nanomaterials, enzymes, supramolecular ensembles) are assembled ITIES, either spontaneously or following application interfacial Galvani potential difference. While primarily used for electrocatalysis oxygen reduction reaction (ORR) hydrogen evolution (HER), recent work has focused on (OER) electrocatalytic oxidation elemental sulfur (S8) organosulfur compound. Protocols compare performances ITIES call careful data analysis a detailed knowledge catalyst’s morphological parameters (e.g., active surface area catalyst loading). However, standardisation such protocols yet be implemented required allow better comparison results from individual biphasic systems.
