“…Electrochemistry at the interface between two immiscible electrolyte solutions (ITIES) found different applications over the years that include oxygen reduction, [1][2][3] metal ion extraction, [4,5] water oxidation, [6] metal deposition, [7][8][9] electrocatalysis [10][11][12][13] and analytical assays for quantification of a vast number of analytes. [14][15][16][17][18][19][20][21][22][23] The success of this technology arises from the fundamental improvements introduced in the ITIES systems over the last decades, such as the four electrode potentiostats [24] for better potential control and reproducible measurements, the reduction of the interface size [25][26][27][28][29][30][31][32][33] from macrointerfaces to microinterfaces to improve the sensitivity and the gelation of the organic phase [34][35][36] that enhanced the stability the liquid-liquid systems.…”

The field of electrochemistry at the interface between two immiscible electrolyte solutions (ITIES) has been continuously expanding over the years due to their vast number of applications, including to investigate the partitioning of ionizable drugs at liquid‐liquid systems. The aim of this Review is to highlight the great potential of ITIES as simple model of biological membranes to gather information on drug partition, lipophilicity, and pharmacokinetics that can be very useful for researchers in the field of drug discovery for development of new drugs with enhanced permeability. Relevant contributions and perspectives to improve the applicability of ITIES in partition studies were highlighted and discussed. The second part of this Review pretends to highlight the application of electrochemistry at the ITIES as experimental technique to investigate interactions between small ligands, including drugs, and DNA, a topic of high research interest in pharmaceutical and biological sciences, which remains with lots of opportunities to explore.

The electrochemical conversion of oxygen to water is a crucial process required for renewable energy production, whereas its first two-electron step produces a versatile chemical and oxidanthydrogen peroxide. Improving performance and widening the limited selection of the potential catalysts for this reaction is a step toward the implementation of clean-energy technologies. As silver is known as one of the most effective catalysts of oxygen reduction reaction (ORR), we have designed a suitable molecular precursor pathway for the selective synthesis of metallic (Ag), intermetallic (Ag3Sb), and binary or ternary metal sulfide (Ag2S and AgSbS2) nanomaterials by judicious control of reaction conditions. The decomposition of xanthate precursors under different reaction conditions in colloidal synthesis indicates that carbon–sulfur bond cleavage yields the respective metal sulfide nanomaterials. This is not the case in the presence of trioctylphosphine when the metal–sulfur bond is broken. The synthesized nanomaterials were applied as catalysts of oxygen reduction at the liquid–liquid and solid–liquid interfaces. Ag exhibits the best performance for electrochemical oxygen reduction, whereas the electrocatalytic performance of Ag and Ag3Sb is comparable for peroxide reduction in an alkaline medium. Scanning electrochemical microscopy (SECM) analysis indicates that a flexible 2-electron to 4-electron ORR pathway has been achieved by transforming metallic Ag into intermetallic Ag3Sb.
