The optimal heterogeneous catalyst for an acid-base reaction

Hervé Toulhoat

Different iron species exhibit distinct activity and selectivity in CO2 hydrogenation reaction. Herein, by controlling calcination temperature, Fe-Al interaction in Na promoted Fe-Al catalysts has been regulated, which further leads to various compositions of iron oxide (FeOx) and iron carbides (…

Activity of molybdenum and tungsten oxycarbides in hydrodenitrogenation of carbazole leading to isomerization secondary reaction of bicyclohexyl. Results using bicyclohexyl as feedstock

Marek Lewandowski, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activities of bulk tungsten and molybdenum oxycarbides, (W2C and Mo2C) have been specifically studied in the isomerization occurring during the hydrodenitrogenation (HDN) of carbazole. The two catalysts have been characterized by several physico-chemical techniques such as X-Ray…

Tough thiourethane thermoplastics for fused filament fabrication

Gregory Ellson, Xavier Carrier, Jamie Walton, Samsuddin Faisal Mahmood, Kejia Yang, Joshua Salazar, Walter Voit

Fused filament fabrication (FFF) is the most common form of additive manufacturing. Most FFF materials are variants of commercially available engineering plastics. Their performance when printed can widely vary, thus there is an increasing volume of research on alternative materials with thermal…

Preparation, characterization, and hydrogenation activity of new Rh 0 –MCM-41 catalysts prepared from as-synthesized MCM-41 and RhCl 3

Maya Boutros, Georges Moarbess, Thomas Onfroy, Franck Launay

Impregnation of as-synthesized MCM-41 silica by ethanolic solutions of rhodium(III) chloride was tested as an alternative to its introduction into the synthesis gel to get, after calcination and reduction by H2, highly dispersed metal(0) nanoparticles throughout the mesopores network. Rh(III) and…

Preparation of thin film gold based catalysts for oxidation reactions in liquid and gas phases

Anne-Félicie Lamic-Humblot, Philippe Barthe, Guillaume Guzman, Laurent Delannoy, Catherine Louis

This work deals with the preparation of gold on titania catalysts to make catalytic films in the less than 100 nm thickness area and its comparison with usual powder catalyst in catalytic oxidation reactions in gas and liquid phases. Titania was coated on glass plates with different thicknesses,…

Surface passivation of aluminum alloy 6061 with gaseous trichlorosilane: A surface investigation

Rickielle Ngongang, Eric Marceau, Xavier Carrier, Claire-Marie Pradier, Christophe Méthivier, Jean-Luc Blanc, Martine Carré

A molecular-scale investigation of the interaction at room temperature between gaseous trichlorosilane (HSiCl3), used as a passivating agent, and surfaces of aluminum alloy AA6061 in a polished or hydroxylated state is conducted. Atomic force microscopy (AFM) and scanning electron microscopy (SEM)…

Effect of SAM chain length and binding functions on protein adsorption: β-Lactoglobulin and apo-transferrin on gold.

Erin E. Bedford, Vincent Humblot, Frank X. Gu, Claire-Marie Pradier

Controlled immobilization of proteins is crucial in many applications, including biosensors. Allergen biosensing, for example, requires molecular recognition of suitably immobilized proteins by specific antibodies and sensitive measurement of this interaction. Self-assembled monolayers (SAMs),…

Alkaline Earth metals (Mg, Sr, and Ca) were incorporated into the dealuminated mesoporous beta zeolite (DeAlBeta) by the two-step postsynthesis method. Physicochemical properties of both unmodified and alkaline Earth metal-modified DeAlBeta zeolite were characterized by XRD, DR UV-vis, FTIR, TPD of…
