Discrimination of Surface and Bulk Structure of Crystalline Hydroxyapatite Nanoparticles by NMR

Manel Ben Osman, Sarah Diallo-Garcia, Virginie Herledan, Dalil Brouri, Tetsuya Yoshioka, Jun Kubo, Yannick Millot, Guylène Costentin

Solid state 1H and 31P NMR spectroscopy was used to characterize well-crystallized hydroxyapatite samples of different stoichiometry prepared by a precipitation route. The aim of the paper was to investigate the bulk structural features of samples with different stoichiometry and to discriminate…

Atomic level characterization and sulfur resistance of unsupported W2C during dibenzothiophene hydrodesulfurization. Classical kinetic simulation of the reaction

Marek Lewandowski, Agnieszka Szymanska-Kolasa, Céline Sayag, Patricia Beaunier, Gérald Djéga-Mariadassou

The stability of unsupported W2C tungsten carbide and its sulfur resistance during hydrodesulfurization (HDS) of dibenzothiophene (DBT) are a specificity of W2C. This material was characterized by X-ray diffraction, specific surface area measurements, HRTEM associated with EDS, lattice images,…

A co-templating route to the synthesis of Cu SAPO STA-7, giving an active catalyst for the selective catalytic reduction of NO

A. Lorena Picone, Stewart J Warrender, Alexandra M Slawin, Daniel M Dawson, Sharon E Ashbrook, Paul A Wright, Stephen P Thompson, Lucia Gaberova, Philip L Llewellyn, Beatrice Moulin, Alexandre Vimont, Marco Daturi, Min Bum Park, Sam Kyung Sung, In-Sik Nam, Suk Bong Hong

Copper cyclam (cyclam = 1,4,8,11-tetraazacyclotetradecane) and tetraethylammonium (TEA(+)) act as co-templates for the hydrothermal crystallisation of the silicoaluminophosphate SAPO STA-7, as determined by UV-visible, ESR and solid-state MAS NMR spectroscopies, powder and single crystal X-ray…

Self-Assembly of Fatty Acids on Hydroxylated Al Surface and Effects of Their Stability on Wettability and Nanoscale Organization

Irma Liascukiene, Marie Steffenhagen, Svajus J. Asadauskas, Jean-François Lambert, Jessem Landoulsi

The self-assembly of fatty acids (FA) on the surfaces of inorganic materials is a relevant way to control their wetting properties. While the mechanism of adsorption on model flat substrate is well described in the literature, interfacial processes remain poorly documented on nanostructured…

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…

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…
