A new method for elaborating mesoporous SiO 2 /montmorillonite composite materials

Khalil Tesnime Abou, Chaabene Semy Ben, Boujday Souhir, Blanchard Juliette, Bergaoui Latifa

We report the sol–gel preparation of SiO 2 / montmorillonite composite materials and the investigation of the effect of the amount of clay and the TEOS concentration on the textural and structural properties of the composites. Pre-swelling of the clay with cetyltrimethyl ammonium results in solids…

Methanol Oxidation to Formaldehyde on VSiBEA Zeolite: A Combined DFT/vdW/Transition Path Sampling and Experimental Study

Diana C. Tranca, Frerich J. Keil, Ionut Tranca, Monica Calatayud, Stanislaw Dzwigaj, Maciej Trejda, Frederik Tielens

Density functional calculations have been performed applying periodic boundary conditions to investigate the oxidation of methanol on vanadium-containing SiBEA zeolite (VSiBEA). Different types of reaction configurations have been set up in conformity with the experimental conditions. Thermodynamic…

Les Hydroxyapatites, un système basique atypique modulable par la synthèse : vers l'identification des sites actifs, Hydroxyapatites, an atypical basic system tuneable by synthesis: toward the identification of active sites

Sarah Diallo Garcia

Les Hydroxyapatites (HAp) sont des matériaux basiques dont les propriétés catalytiques atypiques, notamment leur très bonne sélectivité pour la transformation de l'éthanol en n-butanol, sont encore mal rationnalisées. La modulation de leur paramètres de synthèse ainsi leur aptitude à la…, Hydroxyapatites (HAp) are basic materials whose atypical catalytic properties, in particular their high selectivity in n-butanol from ethanol's conversion, are yet to be rationalised. Modulation of their synthesis parameters as well as their ability toward substitution allowed us to use their…

Investigation of ion-selective electrodes with neutral ionophores and ionic sites by EIS. I. Theory

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

Models of an ion selective electrode involving an ionophore and mobile sites in a membrane are proposed. The first model, called the phase boundary potential model, supposed thermodynamic equilibrium; it allows the concentrations of the various species to be calculated. Then, a kinetic model, which…

Role of Water on the Activity of Magnesium Silicate for Transesterification Reactions

Longfei Lin, Damien Cornu, Maya Mounir daou, Cyril Domingos, Virginie Herledan, Jean-Marc Krafft, Guillaume Laugel, Yannick Millot, Hélène Lauron-Pernot

This study aims to reveal how water adsorbed on to a solid can influence its catalytic properties for transesterification in liquid phase. A commercial magnesium silicate was subjected to a range of thermal pretreatments and used for the transesterification of ethyl acetate with methanol.…

A microGC study of the deactivation process during conversion of methylbutynol on basic zeolites

Pascale Massiani, Jean-François Groust, Guylène Costentin, Laurent Teyssier

The initial deactivation occurring during conversion of methylbutunol on basic alkali-faujasite catalysts was studied by microGC. Both the product selectivity and the formation of water during the first minutes of run permit to conclude on the deactivation process and on the nature of the adsorbed…
