Advances in the preparation of supported gold catalysts: Mechanism of deposition, simplification of the procedures and relevance of the elimination of chlorine

Antoine Hugon, Nadia El Kolli, Catherine Louis

The paper focuses on the chem. mechanisms involved during the prepn. of gold catalysts supported on alumina and titania and on attempts to simplify the procedures of prepn. Three methods involving the same gold loading (1 wt%) and the same precursor, HAuCl4, were studied: impregnation in excess of…

Ta(V)-Single Site BEA Zeolite by Two-Step Postsynthesis Method: Preparation and Characterization

Stanislaw Dzwigaj, Yannick Millot, Michel Che

Ta(1.0)SiBEA and Ta(2.0)SiBEA zeolites are prepared by a two-step postsynthesis method involving first the creation of vacant T-atom sites associated with silanol groups by dealumination of TEABEA zeolite with nitric acid and then the impregnation of the resulting SiBEA zeolite with tantalum…

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…
