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…

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…

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…

An Anthropocene-Framed Transdisciplinary Dialog at the Chemistry-Energy Nexus

Mathieu S Prévot, Valeria Finelli, Xavier Carrier, Gabriele Deplano, Margherita Cavallo, Elsje Alessandra Quadrelli, Juliette Michel, Marie-Hélène Pietraru, Clément Camp, Giulia Forghieri, Anna Gagliardi, Sebastian Seidel, Antoine Missemer, Bertrand Reuillard, Barbara Centrella, Silvia Bordiga, María Grace Salamanca González, Vincent Artero, Keanu V. A. Birkelbach, Niklas von Wolff

At the energy-chemistry nexus, key molecules include carbon dioxide (CO2), hydrogen (H2), methane (CH4), and ammonia (NH3). The position of these four molecules and that of the more general family of synthetic macromolecular polymer blends (found in plastics) were cross-analyzed with the planetary…

How Surface Hydroxyls Enhance MgO Reactivity in Basic Catalysis: The Case of Methylbutynol Conversion

Petitjean Hugo, Hazar Guesmi, Lauron-Pernot Hélène, Costentin Guylène, David Loffreda, Philippe Sautet, Françoise Delbecq

This combined experimental and theoretical study aims at understanding why surface hydroxyl groups may enhance catalytic reactivity of MgO surfaces in basic catalysis, whereas hydroxyls are weakly deprotonating groups. We investigated that reactivity enhancement in the catalytic conversion of 2-…

Investigation of ion-selective electrodes with neutral ionophores and ionic sites by EIS. II. Application to K+ detection

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

The impedance of an ion-selective electrode (ISE) to potassium with valinomycin as the ionophore and KBΦ4 as the ionic sites was measured. The membrane was made of PVC with DNP as a plasticizer. The influence of the content of the plasticizer and the membrane thickness was investigated. The…

Control of calcium accessibility over hydroxyapatite by post-precipitation steps: influence on the catalytic reactivity toward alcohols

Manel Ben Osman, Sarah Diallo Garcia, Jean-Marc Krafft, Christophe Methivier, Juliette Blanchard, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Hydroxyapatites are increasingly used as heterogeneous catalysts since they present atypical behaviours for many acid base reactions. The aim of this study was to discuss the possible involvement of Ca2+ Lewis and/or PO–H Brønsted acid sites belonging to the hydroxyapatite system in the conversion…
