Adsorption and photoreactivity of CdSe nanoparticles at liquid|liquid interfaces
Hubert Girault, Bin Su, Jean-Pierre Abid, Nicolas Eugster
The voltage induced assembly and photoreactivity of cadmium selenide (CdSe) nanoparticles protected by mercaptosuccinic acid are studied at the polarisable interface between water and 1,2-dichloroethane electrolyte solutions. Cyclic voltammograms and admit ...
2005Ab initio molecular dynamics simulation of redox reactions of transition metal ions in aqueous solution and proteins
Redox potentials measure the free energy required to transfer a mol. species (ion) between two states of different total charge. In soln. a major contribution to the redox potential is the hydration free energy difference of the ion in the two oxidn. state ...
2005Promotion électrochimique des catalyseurs à base de rhodium et d'iridium
In this thesis, the electrochemical promotion of lr and Rh based catalysts was studied for the complete combustion of ethylene and propylene. The study was performed by using two types of electrocatalytical cells: a classical, pellet type cell and a tubula ...
EPFL2004Dynamic photoelectrochemistry at porphyrin-sensitised liquid/liquid interfaces
The interface between two immiscible electrolyte solutions provides a well-defined framework for fundamental studies of heterogeneous charge transfer processes. Recent developments in experimental methodology have allowed addressing the kinetics of electro ...
EPFL2004Effect of the Phase Volume Ratio on the Potential of a Liquid-Membrane Ion-Selective Electrode
Two-phase liquid system IA(w)jIX(o) comprising the interface between the aqueous solution (w) of uni-univalent electrolyte IA and an organic solvent solution (o) of a uni-univalent electrolyte IX with the common cation I+ is considered as a simple model of ...
American Chemical Society2004Electrochemical oxidation of ethylenediaminetetraacetic acid (EDTA) on BDD electrodes: Application to wastewater treatment
Christos Comninellis, Lassine Ouattara, Ilaria Duo
The electrochem. oxidn. of EDTA was studied at boron-doped diamond (BDD) electrodes. Cyclic voltammetry in the potential region of water stability showed that EDTA is oxidized in an irreversible 2-electron-transfer mechanism. No fouling phenomena were noti ...
2003Control of electron transfer kinetics at boron-doped diamond electrodes by specific surface modification
Diamond films with different levels of doping have been the subject of applications and fundamental research in electrochemistry, opening up a new branch known as the electrochemistry of diamond. The electrochemical properties of diamond mostly depend on t ...
EPFL2003Organization and Reactivity of Nanoparticles at Molecular Interfaces. Part I. Photoelectrochemical Responses Involving TiO2 Nanoparticles Assembled at Polarizable Water|1,2-Dichloroethane Junctions
Hubert Girault, Jacques-Edouard Moser
The photoelectrochemical properties of TiO2 anatase nanoparticles were studied at the water|1,2-dichloroethane (DCE) interface under potentiostatic control. The interfacial concentration of the electrostatically stabilized particles can be effectively tune ...
American Chemical Society2002Numerical modelling of potential and current distributions in a bipolar electrolytic cell
This work deals with the modelling of electrochemical reactors with bipolar electrodes. We give a numerical model which enables us to compute electrical current and potential distributions in an electrochemical cell of any type of geometry in two and three ...
EPFL1998Use of Zr/ZrO2 as a counter electrode for the minimization of loss reactions in single-compartment electrolysis cells
The use of ZrO2 membrane on counter electrodes (e.g. Zr) is proposed for controlling the mass transfer rates to the electrode and therefore the extent of possible loss reactions. A comparative study was undertaken to examine the influence of the prepn. tec ...
