Dégradation chimique et mécanique de l'alumine en phase aqueuse : mécanisme et inhibition en conditions ambiantes et hydrothermales, Chemical and mechanical degradation of alumina in aqueous phase : mechanism and inhibition in ambient and hydrothermal conditions

Jane Abi Aad

L'alumine, utilisée comme support de catalyseurs pour la réaction de Fischer-Tropsch ou pour la conversion de la biomasse, se transforme partiellement en présence d'eau en phases (oxy)hydroxydes à l'origine de fines qui posent problème dans la mise en ¿uvre de procédés en réacteurs…, Alumina, used as a catalyst support for the Fischer-Tropsch reaction or for the conversion of biomass, partially transforms in presence of water into (oxy)hydroxides phases. The formation of the latter leads to the production of fine particles that may cause plugging problems in the implementation…

Characterization of Phosphate Species on Hydrated Anatase TiO2 Surfaces

Frederik Tielens, Christel Gervais, Géraldine Deroy, Maguy Jaber, Lorenzo Stievano, Cristina Coelho Diogo, Jean-Francois Lambert

The adsorption/interaction of KH2PO4 with solvated (100) and (101) TiO2 anatase surfaces is investigated using periodic DFT calculations in combination with GIPAW NMR calculations and experimental IR and solid state 17O, and 31P NMR spectroscopies. A complete and realistic model has been used to…

Adsorption and thermal condensation mechanisms of amino acids on oxide supports : I. Glycine on silica

Ming Meng, Lorenzo Stievano, Jean-François Lambert

Glycine was adsorbed on the surface of a well-defined silica from aqueous solutions of variable concentrations and pHs. The adsorbed molecules were characterized using middle-IR and UV-vis-NIR spectroscopies. Except at the lowestpH(2.0), they were predominantly present on the surface as zwitterions…

Effect of Impregnation with Ammonia vs Silica Support Textural Properties on Ni Nanoparticle Catalysts for Dry Reforming of Methane

Oscar Daoura, Nissrine El Hassan, Maya Boutros, Sandra Casale, Pascale Massiani, Franck Launay

In this work, Ni(0) nanoparticles (3.5 and 5 wt %) highly dispersed on silica were obtained by reducing the calcined solid resulting from the impregnation of a nonporous siliceous support (here Aerosil-380) by aqueous nickel(II) nitrate in the presence of aqueous ammonia. The great effect of that…

Characterizations and performances of Ni/diatomite catalysts for dry reforming of methane

Karam Jabbour, Nissrine El Hassan, Anne Davidson, Pascale Massiani, Sandra Casale

Monometallic 5 wt% Ni containing catalysts were prepared by a two-solvent (cyclohexane/water) deposition method using cheap and widely available natural diatomites (Ni/AW2 and Ni/MN3) as supports. The fresh samples were characterized by SEM, EDX microanalysis, N2 adsorption–desorption isotherms,…

Study of gold electrodissolution by scanning electrochemical microscopy in different modes

Divino Salvador Ramírez-Rico, Michel Keddam, Erika Roxana Larios-Durán, Vincent Vivier

The electrodissolution of gold has already been widely studied by several methods, but no consensus concerning the reaction mechanism has been reached. In this work, the scanning electrochemical microscopy (SECM) has been used in transient condition for studying the electrodissolution of gold in…

l-Methionine adsorption on Cu(110), binding and geometry of the amino acid as a function of coverage

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

The adsorption of l-methionine on Cu(110) has been characterized by combining in situ Polarization Modulation Infrared Reflection Absorption Spectroscopy (PM-IRRAS) and X-ray Photoelectron Spectroscopy (XPS). Both the chemical state of the molecule, and its anchoring points were determined at…

Investigation of ionic surfactant-selective electrodes by EIS

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

A model of ionic surfactant-selective electrodes with mobile ionic sites is proposed. The steady-state concentrations of the active species are calculated. The electrochemical impedance of the membrane immersed between electrolytic solutions is given. This model is in good agreement with the…
