Oxygen and proton reduction by decamethylferrocene in non-aqueous acidic media

Hubert Girault, Anne-Clémence Corminboeuf, Manuel Alejandro Méndez Agudelo, Bin Su, Peiyu Ge, Zdenek Samec, Imren Hatay

Experimental studies and density functional theory (DFT) computations suggest that oxygen and proton reduction by decamethylferrocene (DMFc) in 1,2-dichloroethane involves protonated DMFc, DMFcH+, as an active intermediate species, producing hydrogen perox ...

Voltammetry for surface-active ions at polarisable liquid|liquid interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su

Adsorption of charged species at the interface between two immiscible electrolyte solutions (ITIES) is simulated taking into account both the mutual influence between the potential dependent surface excess charge and the potential distribution between the ...

Proton-Coupled Oxygen Reduction at Liquid-Liquid Interfaces Catalyzed by Cobalt Porphine

Hubert Girault, Manuel Alejandro Méndez Agudelo, Imren Hatay, Fengping Li, Zdenek Samec

Cobalt porphine (CoP) dissolved in the organic phase of a biphasic system is used to catalyze O2 reduction by an electron donor, ferrocene (Fc). Using voltammetry at the interface between two immiscible electrolyte solutions (ITIES), it is possible to driv ...

About the Electrospray Ionization Source in Mass Spectrometry: Electrochemistry and On-chip Reactions

Hubert Girault, Niels Erik Lion, Christophe Roussel, Manuel Alejandro Méndez Agudelo, Michel Prudent, Joël Stéphane Rossier, Bin Su

The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal ions and b ...

Biphasic Electrospray Ionization for the Study of Interfacial Complexes

Hubert Girault, Manuel Alejandro Méndez Agudelo, Michel Prudent

Biphasic electrospray ionization (BESI) mass spectrometry is achieved by using a dual-channel microsprayer, where channels filled with different immiscible phases meet at the Taylor cone. Two types of interfacial complexation reactions have been studied: t ...

Peptide-Phospholipid Complex Formation at Liquid-Liquid Interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Michel Prudent, Bin Su

Two peptides known to interact with receptors embedded in cell membranes, angiotensin III (AngIII) and Leuenkephalin(LeuEnk), were studied electrochemically at the interface formed between two immiscible electrolyte solutions modified by an adsorbed monola ...
