The Catalytic Performance of Ni-Co/Beta Zeolite Catalysts in Fischer-Tropsch Synthesis

Renata Sadek, Karolina Chalupka, Pawel Mierczynski, Waldemar Maniukiewicz, Jacek Rynkowski, Jacek Gurgul, Magdalena Lasoń-Rydel, Sandra Casale, Dalil Brouri, Stanislaw Dzwigaj

The influence of nickel introduction on the catalytic performance of cobalt micro-and mesoporous Beta zeolite catalysts in Fischer-Tropsch Synthesis was studied. Catalysts containing 3 wt% of nickel and 10 wt% of cobalt were prepared by co-impregnation and sequential impregnation and…

Site-specific grafting on titanium surfaces with hybrid temporin antibacterial peptides

Nicolas Masurier, Jean-Baptiste Tissot, Douae Boukhriss, Said Jebors, Coline Pinese, Pascal Verdié, Muriel Amblard, Ahmad Mehdi, Jean Martinez, Vincent Humblot, Gilles Subra

Relying on a membrane-disturbing mechanism of action and not on any intracellular target, antimicrobial peptides (AMP) are attractive compounds to be grafted on the surface of implantable materials such as silicone catheters or titanium surgical implants. AMP sequences often display numerous…

Covalent immobilization of glucose oxidase on mesocellular silica foams: Characterization and stability towards temperature and organic solvents

Noemie Balistreri, Dorian Gaboriau, Claude Jolivalt, Franck Launay

Glucose oxidase (GOx) immobilization onto mesoporous SBA-15 silica and two mesocellular foams (MCF) characterized by similar surface area and pore volumes but different pore/cell dimensions was examined. The covalent grafting of the enzyme through amide bonds was evidenced by controlling pH…

Characterization of Supported Vanadium Oxide Species on Silica: A Periodic DFT Investigation

Mazharul M. Islam, Dominique Costa, Monica Calatayud, Frederik Tielens

The geometry, energetic, and spectroscopic properties of molecular structures of silica-supported vanadium oxide catalysts are studied using periodic density functional calculations. Isolated vanadia units deposed on amorphous silica are modeled at low coverage, 0.44 atoms nm(-2). The models are…

Exploring the reactivity of mixed omega-functionalized undecanethiol self-assembled monolayers - A DFT study

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier

The reactive sites of self-assembled monolayers (SAM) formed by substituted thiolalkyl chains have been predicted in the case of the pure mercaptoundecane acid, for the pure mercaptoundecane alcohol, and the mixed 1:1 SAMs. The differences in reactivity between the different SAM domains (pure and…

Recent development of heterogeneous catalysis in ring-opening, biocatalysis, and selective partial oxidation reactions on metal oxides

Ioana Fechete, Jacques C. Védrine

In this review article, we analyze the state of the art and future developments in three important domains of heterogeneous catalysis, namely ring opening, biocatalysis, and partial oxidation on metal oxides. After recollecting the scientific bases of each domain, we consider several examples, some…

A new route for preparing nanoporous Cu–Zn–Ni–Co alloy by electrodeposition and dealloying: Application as electrocatalysts for water reduction

Yuelin Xie, Antoine Miche, Vincent Vivier, Mireille Turmine

<div><p>Nanoporous Cu-Zn-Ni-Co alloys have been prepared on Cu foils by a two-step electrodeposition mechanism in ethylammonium nitrate (EAN), a protic ionic liquid, and ethaline, a deep eutectic solvent (DES). A porous alloy was then produced using a dealloying step. The…

Characterization of as-synthesized MOx-MCM-41 (M=Mo, W) mesophases using Raman spectrometry and 29Si MAS NMR.

J.-V. Piquemal, E. Briot, G. Chottard, P. Tougne, J.-M. Manoli, J.-M. Brégeault

MCM-41 mesostructured silicas containing molybdenum and tungsten have been prepared in an acidic medium at room temperature. Two procedures were considered: the so-called oxo–peroxo route with low-nuclearity peroxo metal precursors (route A) and the oxo–polyoxo pathway, involving or generating…

Towards the synthesis of mixed oxides with controlled stoichiometry from Prussian blue analogues

Virgile Trannoy, Amélie Bordage, Jordan Dezalay, Romuald Saint-Martin, Eric Rivière, Patricia Beaunier, Cédric Baumier, Camille La Fontaine, Giulia Fornasieri, Anne Bleuzen

Controlling the synthesis of mixed oxides is of great interest since their stoichiometry influences the properties. We present here the transformation of the Co4[Fe(CN)6]2.7 Prussian blue analogue (PBA) into the mixed Co1.8Fe1.2O4 spinel oxide, with a detailed characterization of the final phase (…

Facile synthesis of palladium nanowires by a soft templating method

Prem Siril, Anaïs Lehoux, Laurence Ramos, Patricia Beaunier, Hynd Remita

Very long and thin monocrystalline Pd nanowires were synthesized by decomposition using hydrazine vapour treatment of Pd2(DBA)3 confined in the oil phase of a hexagonal mesophase. The mesophase is composed of toluene-swollen tubes, doped with the Pd precursor, stabilized by a monolayer of…
