“…These processes include the deposition of a metal such as Cu at the ITIES [142], the preparation of colloidal metal particles with catalytic properties for homogeneous organic reactions [143], electropolymerization [144], and electron transfer through a ground [145] or excited state localized at the ITIES (photocatalysis) [146], cf. also Fig.…”

This document provides an inventory of theoretical and methodological concepts in electrochemistry at the interface between two immiscible electrolyte solutions (ITIES). Definitions of basic relationships are given, together with recommendations for the preferred symbols, terminology, and nomenclature. Methods of study of ITIES are briefly described, current experimental problems are indicated, and representative experimental data are shown. The practical applications of electrochemistry at ITIES are summarized. CONTENTS

“…The drawback of studying nucleation and growth through electrochemistry on a solid electrode is the presence of defects on the electrode surface which act as preferential nucleation sites causing heterogeneity within the reaction [19]. An alternative is to study the processes occurring at a liquid/liquid interface [20], where the interface between the two immiscible fluid phases provides a defect free substrate to follow the nucleation. The reaction at the liquid/liquid interface is considered analogous to that at a liquid/solid interface, i.e.…”

We report the use of XAFS (X-ray absorption fine structure) as an in situ method to follow the electrochemically driven deposition of palladium nanoparticles at a liquid/liquid interface.A novel glass/plastic hybrid electrochemical cell was used to enable control of the potential applied to the liquid/liquid interface. In situ measurements indicate that the nucleation of metallic nanoparticles can be triggered through chronoamperometry or cyclic voltammetry.Page 2 of 37 A c c e p t e d M a n u s c r i p tIn contrast to spontaneous nucleation at the liquid/liquid interface, whereby fluctuations in Pd oxidation state and concentration are observed, under a fixed interfacial potential the growth process occurs at a steady rate leading to a build-up of palladium at the interface. Raman spectroscopy of the deposit suggests that the organic electrolyte binds directly to the surface of the deposited nanoparticles. It was found that the introduction of citric acid results in the formation of spherical nanoparticles at the interface.

“…The first evidence of electron transfer at liquid/liquid interfaces were found by Guainazzi et al (Girault, 1993;Guainazzi, 1975). They could reduce Cu(III) in aqueous phase to Cu(0) using hexacarbonylvanadate tetrabutylammonium in 1,2-dichloroethane.…”
