Nano-engineered hierarchical porous silicas for enhanced catalytic efficiency in the liquid phase

Abdelali Zaki, M. Wastiaux, Sandra Casale, Alexandre Mussi, Jean-François Dhenin, Christine Lancelot, Jean-Philippe Dacquin, Pascal Granger

By tailoring the pore properties (size, morphology and orientation) of hierarchical catalysts, we show experimentally the importance of active phase accessibility on catalytic efficiency. This finding likely contributes to a better rationalisation of the structure sensitivity of the nitrite…

Dispersion and states of platinum ions in BEA-zeolite pores: effect of the framework basicity

C. Bisio, Katia Fajerwerg, J. Krafft, P. Massiani, G. Martra

Pt/Cs-BEA materials prepared by a classical ion-exchange procedure using two Cs-BEA supports with different Cs loadings, and a reference acidic Pt/H-BEA, have been studied to investigate the effect of the framework basicity (evaluated by FT-IR of adsorbed CO2) on the state of platinum species after…

La lutte contre l’adhérence et la prolifération de bactéries sur les surfaces constitue une préoccupation constante et un enjeu médical et socio-économique majeur de notre société. Cette biocontamination est responsable de nombreuses infections entraîne également une détérioration des propriétés…, The fight against the adhesion and proliferation of bacteria on surfaces is a constant concern and a major medical and socio-economic issue for our society. This biocontamination is responsible for many infections, also leading to a deterioration of the structural and functional properties of…

Influence of partial dealumination of BEA zeolites on physicochemical and catalytic properties of AgAlSiBEA in H2-promoted SCR of NO with ethanol

Nataliia O. Popovych, Pavlo I. Kyriienko, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

The two-step postsynthesis method allows obtaining AlSiBEA zeolites with different degree of dealumination (Si/Al = 100 and 200). Physicochemical properties (crystallinity, hydroxyl group coverage, acidic sites and nature of silver species) of AlSiBEA and AgAlSiBEA were investigated by XRD, DR UV–…

Selective Hydrogenation of 1,3-Butadiene in the Presence of an Excess of Alkenes over Supported Bimetallic Gold-Palladium Catalysts

Antoine Hugon, Laurent Delannoy, Jean-Marc Krafft, Catherine Louis

Supported Au catalysts modified by the addition of low amount of Pd (Au/Pd atomic ratio >= 10), prepared by either codeposition-precipitation (DP) or coimpregnation in excess of solution (IES), result in the formation of bimetallic Au Pd particles that promote the selective hydrogenation of…

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…

Deciphering the improvement in (H2-)C3H6-SCR performance of Ag/Al2O3 catalysts prepared from warm-water-treated alumina: A NMR-assisted identification of the Ag anchoring sites of the alumina support

Yannick Millot, Guylène Costentin, Clémence Rodigue, Thomas Onfroy, Cyril Thomas

Lean exhausts aftertreatment has been the subject of numerous investigations due to ever stringent regulations on pollutants emissions such as that of NOx. Among aftertreatment technologies, the selective catalytic reduction of NOx by the hydrocarbons (HC-SCR) has been studied intensively, in…

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…
