Detection of hydrogen peroxide produced at a liquid/liquid interface using scanning electrochemical microscopy

Hubert Girault, Fernando Cortes Salazar, Bin Su

Scanning electrochemical microscopy (SECM) was used to monitor in situ hydrogen peroxide (H2O2) produced at a polarized water/1,2-dichloroethane (DCE) interface. The water/DCE interface was formed between a DCE droplet containing decamethylferrocene (DMFc) ...

Molecular Electrocatalysis for Oxygen Reduction by Cobalt Porphyrins Adsorbed at Liquid/Liquid Interfaces

Hubert Girault, Pierre-Alain Carrupt, Bin Su, Imren Hatay

Molecular electrocatalysis for oxygen reduction at a polarized water/1,2-dichloroethane (DCE) interface was studied, involving aqueous protons, ferrocene (Fc) in DCE and amphiphilic cobalt porphyrin catalysts adsorbed at the interface. The catalyst, (2,8,1 ...

Redox Properties of Self-Assembled Gold Nanoclusters

Hubert Girault, Bin Su

The redox properties of a monolayer of alkanethiolate-protected gold nanoclusters (MPCs) constructed on a gold slide electrode was studied in 1,2-dichloroethane (DCE) electrolyte solutions. The influence of the electrostatic interaction between attached MP ...

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 ...

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 ...

Assembly and reactivity of nanoparticles at liquid / liquid interfaces

Bin Su

The interface between two immiscible electrolyte solutions (ITIES), or liquid|liquid interface, provides a defect-free junction for fundamental studies of adsorption phenomena, heterogeneous charge transfer reactions, and phase-formation processes. Recent ...

Evidence of tetraphenylporphyrin monoacids by ion-transfer voltammetry at polarized liquid|liquid interfaces

Hubert Girault, Bin Su

We present a simple methodology to illustrate the existence of tetraphenylporphyrin monoacid based on ion-transfer voltammetry at a polarized water|1,2-dichloroethane interface and organic pK values are also estimated. ...

SECM photography

Hubert Girault, Fernando Cortes Salazar, Bin Su, Mohamad Hojeij

A novel strategy for imaging commercial black-and-white negative photo films by scanning electrochemical microscopy (SECM) is demonstrated. The imaging is based on using IrCl3 6 as the redox mediator to dissolve silver grains. The SECM probe is biased at a ...

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 ...
