3D-ITIES supported on porous reticulated vitreous carbon

Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster

A thin aqueous film prepared by layer-by-layer assembly of oppositely charged polypeptides on 4-aminobenzoic acid modified porous reticulated vitreous carbon (RVC) electrodes was used with the aim of forming a 3D-ITIES. The film containing a redox mediator ...

The heterodimer formed by electrostatic association of zinc(II) meso-tetrakis(N-methylpyridyl)porphyrin (ZnTMPyP) and zinc(II) meso-tetrakis(p-sulfonatophenyl)porphyrin (ZnTPPS) exhibits a strong affinity for the interface between water and 1,2-dichloroeth ...

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 ...

Simulations of the adsorption of ionic species at polarisable liquid liquid interfaces

Hubert Girault, Bin Su, Nicolas Eugster

The adsorption of ions at the interface between two immiscible electrolyte solutions (ITIES) is primarily controlled by the potential distribution across the interface, which in turn is influenced by the adsorption process. In the present paper, we simulat ...

Reactivity of Monolayer-Protected Gold Nanoclusters at Dye-Sensitized Liquid/Liquid Interfaces

Hubert Girault, Bin Su, Nicolas Eugster

Hexanethiolate monolayer-protected gold nanoclusters (MPCs) were used as redox quenchers at the polarizable water/1,2-dichloroethane (DCE) interface. Photocurrent responses originating from the heterogeneous quenching of photoexcited water soluble porphyri ...

A generalised model for dynamic photocurrent responses at dye-sensitised liquid|liquid interfaces

Hubert Girault, Nicolas Eugster, Zdenek Samec

The heterogeneous photoinduced electron transfer involving dyes adsorbed at the interface between two immiscible electrolyte solutions and redox molecules located in the adjacent phase manifests itself as photocurrent responses under potentiostatic conditi ...

Dynamic photoelectrochemistry at porphyrin-sensitised liquid/liquid interfaces

Nicolas Eugster

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 ...
