Complementarity of Density Functional Theory and Nuclear Magnetic Resonance Tools To Probe the Nano-Layered Silicates Surface Chemistry and Morphology

Mathilde Poirier, Yannick Millot, Elisa Silva Gomes, Maguy Jaber, Virginie Herledan, Guillaume Laugel, Pierre Micoud, François Martin, Hélène Lauron-Pernot, Hervé Toulhoat

By combining experimental, spectroscopic, structural, and physical characterizations and extensive density functional theory simulations, unprecedented insight is gained on the local surface properties of synthetic talc nanoparticles, their structure, morphology and particle size distribution.…

Investigation of the interface in silica-encapsulated liposomes by combining solid state NMR and first principles calculations.

Nicolas Folliet, Claire Roiland, Sylvie Bégu, Anne Aubert, Tzonka Mineva, Annick Goursot, Kaliaperumal Selvaraj, Luminita Duma, Frederik Tielens, Francesco Mauri, Guillaume Laurent, Christian Bonhomme, Christel Gervais, Florence Babonneau, Thierry Azaïs

In the context of nanomedicine, liposils (liposomes and silica) have a strong potential for drug storage and release schemes: such materials combine the intrinsic properties of liposome (encapsulation) and silica (increased rigidity, protective coating, pH degradability). In this work, an original…

Fully controlled precipitation of photomagnetic CoFe Prussian blue analogue nanoparticles within the ordered mesoporosity of silica monoliths

Giulia Fornasieri, Merwen Aouadi, Pierrick Durand, Patricia Beaunier, Eric Rivière, Anne Bleuzen

The porosity of ordered mesoporous silica monoliths has been successfully used as nanoreactor for the elaboration of CoFe Prussian blue analogue nanoparticles. The nanocomposite exhibits a reversible photomagnetic effect different from that of typical powdered compounds due to particle size…

Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

Karam Jabbour, Pascale Massiani, Anne Davidson, Sandra Casale, Nissrine El Hassan

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…

Electronic structure investigation of biphenylene films

R. Totani, C. Grazioli, Tiantian Zhang, I. Bidermane, J. Lüder, M. de Simone, M. Coreno, B. Brena, L. Lozzi, C. Puglia

Photoelectron Spectroscopy (PS) and Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy have been used to investigate the occupied and empty density of states of biphenylene films of different thicknesses, deposited onto a Cu(111) crystal. The obtained results have been compared to…

Ethylene production from diluted bioethanol solutions

Ilenia Rossetti, Matteo Compagnoni, Giorgia de Guido, Laura A. Pellegrini, Gianguido Ramis, Stanislaw Dzwigaj

Ethylene production by ethanol dehydration has been investigated over a set of zeolites with BEA structure in acidic form (HAlBEA). The effect on Ni addition (up to 0.03 g/g (3 mass%)) is explored as a means to improve ethylene selectivity limiting the formation of heavier byproducts. The reaction…

Unusual behaviour of Au/ZnO catalysts in selective hydrogenation of butadiene due to the formation of a AuZn nanoalloy

Salim Derrouiche, Camille La Fontaine, Gode Thrimurtulu, Sandra Casale, Laurent Delannoy, Hélène Lauron-Pernot, Catherine Louis

The reaction of selective hydrogenation of butadiene performed in an excess of propene, which has been extensively studied over gold supported on different oxides and exhibited high selectivity to butenes, has been applied to the case of gold (1 wt%) supported on zinc oxide (8 m2 g−1), a strongly…

Influence of the nature and environment of cobalt on the catalytic activity of Co-BEA zeolites in selective catalytic reduction of NO with ammonia

Rafal Baran, Jean-Marc Krafft, Thomas Onfroy, Teresa Grzybek, Stanislaw Dzwigaj

The influence of cobalt environment on the catalytic properties of CoxSiBEA zeolite in selective catalytic reduction of NO with ammonia was studied. Catalysts were prepared by a two-step postsynthesis method which consists, in the first step, of dealumination of parent BEA zeolite to obtain…
