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

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

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 ...

Electrocatalysis at liquid/liquid interfaces

Raheleh Partovi Nia

This thesis is devoted to the study of oxygen reduction reaction catalysed by porphyrins at the interface between two immiscible electrolyte solutions (ITIES). Electrochemical and spectrophotometric techniques are introduced to these interfaces in order to ...

Charge transfer to solvent identified using dark channel fluorescence-yield L-edge spectroscopy

Majed Chergui, Mercedes Hannelore Rittmann-Frank

Aqueous ions are central to catalysis and biological function and play an important role in radiation biology as sources of damage-inducing electrons. Detailed knowledge of solute-solvent interactions is therefore crucial. For transition-metal ions, soft X ...

Ionization and fragmentation of water clusters by fast highly charged ions

Ivano Tavernelli, Pablo Lopez Tarifa

We study the dissociative ionization of water clusters by impact of 12 MeV/u Ni25+ ions. Cold target recoil ion momentum spectroscopy (COLTRIMS) is used to obtain information about stability, energetics and charge mobility of the ionized water clusters. An ...

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

Hubert Girault, Manuel Alejandro Méndez Agudelo, Fengping Li, Imren Hatay, 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 ...

Investigation of the Ligand-Field States of the Hexaammine Cobalt(III) Ion with Quantum Chemical Methods

François Rotzinger

The ligand-field (LF) transition energies of the Co(NH3)(6)(3+) ion have been computed with multiconfiguration quasidegenerate second-order perturbation theory (MCQDPT2). The water solvent was treated with the polarizable continuum model (PCM), and the env ...

Relative Basicities of ortho-, meta-, and para-Substituted Aryllithiums

The relative basicities of aryllithiums bearing methoxy, chlorine, fluorine, trifluoromethyl and trifluoromethoxy substituents at the ortho, meta, and para positions have been assessed. To this end, two aryllithiums of comparable basicity were equilibrated ...

Quantum calculations on the acid catalyzed rearrangements of norborn-5-en-2-one, 7-oxanorborn-5-en-2-one and 7-azanorborn-5-en-2-one - The electron-releasing effect of homoconjugated carbonyl group

Pierre Vogel, Samuele Giani

Protonation of norbom-5-en-2-one gives 6-oxo-2-norbomyl cation (2) as most stable C7H9O+ cation. Quantum calculations at B3LYP/6-31G(d) level (gas phase, 1 atm, 25 degrees C) predict a C-s-structure for 2 that can be represented as an intramolecular pi-com ...

Ruthenium nanoparticles intercalated in hectorite: A reusable hydrogenation catalyst for benzene and toluene

Gabor Laurenczy, André Meister

The cationic organometallic aqua complexes formed by hydrolysis of [(C 6H6)RuCl2]2 in water, mainly [(C6H6)Ru(H2O)3]2+, intercalate into sodium hectorite by ion exchange, replacing the sodium cations between the anionic silicate layers. The yellow hectorit ...
