Toward redox framework single site zeolite catalysts

Stanislaw Dziwag, Michel Che

This paper concerns heterogeneous single site catalysts which are difficult to prepare because of speciation problems related to the two starting components, the solid and the metal precursor solution. A two-step post-synthesis method is used to prepare the V-SiBEA reference system, with vanadium…

Mesoporous materials from zeolite seeds as supports for nickel tungsten sulfide active phases Part 1. Characterization and catalytic properties in hydrocracking reactions

Shuangqin Zeng, Juliette Blanchard, Michèle Breysse, Dadong Li, Hong Nie, Yahua Shib, Xintian Su

MCM-41 aluminosilicate mesostructures (Si/Al = 18) with hexagonal long-range order were assembled from protozeolitic nanoclusters (zeolite seeds) that normally nucleate the crystn. of b-zeolite (BEA). Depending on the duration of the thermal treatment leading to the zeolite seeds, different acidic…

Immobilization of atrazine on gold, a first step towards the elaboration of an indirect immunosensor, characterised by XPS and FT-IRRAS

Michèle Salmain, Natahlie Fischer-Durand, Céline Roche, Claire-Marie Pradier

As part of our long-term goal to design a novel type of immunosensor based on IR transduction, we devised two strategies to immobilize derivatives of the herbicide atrazine on the surface of planar gold substrates. Both strategies take advantage of the well-known formation of self-assembled…

Synthesis of texturally biphasic mesoporous carbon-silica composites and carbons

Cristiam F. Santa, Maguy Jaber, Jean L. Guth, Ligia Sierra

We report a new synthesis of texturally biphasic carbon-silica composites and carbons that exhibit high surface areas (up to 1500 m2 g 1), pore volumes (up to 1.9 cm3 g 1) and mesopores (4.6-6.9 nm). The composite materials have ordered mesoporous carbon domains embedded in a disordered mesoporous…

Unsupported shaped cobalt nanoparticles as efficient and recyclable catalysts for the solvent-free acceptorless dehydrogenation of alcohols

Arnaud Viola, Jennifer Péron, Kamila Kazmierczak, Marion Giraud, Carine Michel, Lorette Sicard, Noémie Perret, Patricia Beaunier, Mickaël Sicard, Michele Besson, Jean-Yves Piquemal

Oxidation of alcohols is a key-reaction for the valorization of biomass compounds, and green processes are preferred to avoid the use or production of toxic compounds. In this context, unsupported nanometer-sized catalysts have emerged as very promising materials for heterogeneous catalysis. In…

Role of active components of an Ag/Al2O3/cordierite catalyst in selective reduction of NO by ethanol

N. A. Popovich, P. I. Kiriienko, S. Solov’ev, S. Orlik, S. Dzwigaj

We show that the activity of silver/aluminum oxide catalysts in selective reduction of nitrogen oxides by ethanol increases as the Al2O3 content increases, and is determined by the optimal silver content for which Ag + cations and Ag n nanoclusters form on the Al2O3 surface. The role of silver in…

Silver species reduction upon exposure of Ag/Al2O3 catalyst to gaseous ethanol: An in situ Quick-XANES study

Elie Sayah, Camille La Fontaine, Valérie Briois, Dalil Brouri, Pascale Massiani

The evolution of supported silver species of a pre-calcined Ag/Al2O3 catalyst was monitored upon thermal treatment under an air flow enriched with 3000 ppm of ethanol (EtOH) using transmission electron microscopy and UV-visible and X-ray absorption spectroscopies. A special focus is put on the…
