Effects of Pd on Catalysis by Au: CO Adsorption, CO Oxidation, and Cyclohexene Hydrogenation by Supported Au and Pd-Au Catalysts

Anthony Ward, Laurent Delannoy, Ruth Hahn, Shane Kendell, Christopher J. Pursell, Catherine Louis, Bert D. Chandler

catalysts has been shown to have beneficial effects on selective hydrogenation reactions, particularly 1,3- butadiene hydrogenation and the hydrogenation of nitroaromatics, especially p-chloronitrobenzene. Appropriate Pd incorporation enhances hydrogenation activity while maintaining the desirable…

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…

Selective hydrogenation of butadiene over TiO2supported copper, gold and gold–coppercatalysts prepared by deposition–precipitation

Laurent Delannoy, Gode Thrimurthulu, Padigapati S. Reddy, Christophe Méthivier, Jaysen Nelayah, Benjaram M. Reddy, Christian Ricolleau, Catherine Louis

Oxide supported copper and gold catalysts are active for the selective hydrogenation of polyunsaturatedhydrocarbons but their low activity compared to palladium catalysts and the deactivation of copper catalystslimit their use. There are only a very limited number of studies concerned with the use…

Organic pollutant adsorption on clay minerals

Jean-François Lambert

This Chapter is focused on the interactions of organic pollutants with clay minerals and related phenomena. It covers a diverse group of xenobiotic organic molecules that include pesticides, pharmaceuticals, industrial pollutants, and dyes. After an initial classification of these molecules…

Novel non-noble bimetallic Cu-Zn/TiO 2 catalysts for selective hydrogenation of butadiene

Zhao Wang, Guillaume Wang, Catherine Louis, Laurent Delannoy

Oxide-supported copper catalysts are active for the selective hydrogenation of polyunsaturated hydrocarbons with high selectivity to alkenes formation, but a low catalytic stability limits its application. The goal of the work was to investigate whether alloying Cu with Zn will improve catalyst…

Zeolite and Silica-based CO2 Adsorbents

Guillaume Laugel, Rogeria Bingre, Benoît Louis

The ever-increasing CO2 concentration in the atmosphere leading to global warming is one of the main problems that mankind has to face in the 21st century. To avoid the fact that sooner or later humanity will directly start to suffer from it, there is an urgent need to reduce the CO2 level by…

Incorporation of Silver Atoms into the Vacant T-Atom Sites of the Framework of SiBEA Zeolite as Mononuclear Ag(I) Evidenced by XRD, FTIR, NMR, DR UV-vis, XPS, and TPR

Stanislaw Dzwigaj, Yannick Millot, Jean-Marc Krafft, Nataliia Popovych, Pavlo Kyriienko

An AgSiBEA zeolite has been prepared by a two-step postsynthesis procedure that consists of first creating the vacant T atom sites with associated silanol groups by treatment of TEABEA zeolite with nitric acid and then impregnating of resulting SiBEA zeolite with an aqueous solution of AgNO3. The…
