IR Operando Study of the Acetylene Effect on the NO Reduction Mechanism on Pd–Rh/CeO2–ZrO2 Three-Way Catalyst

T. Onfroy, O. Marie

The impact of acetylene on the NO reduction mechanism was investigated on a Pd–Rh/CeO2–ZrO2 catalyst. Temperature Program Reaction revealed that C2H2 has a detrimental effect on NO reduction by both H2 and CO. Stationary regime perturbed by C2H2 pulse at different temperatures showed that surface…

Heteroaggregation and Selective Deposition for the Fine Design of Nanoarchitectured Bifunctional Catalysts: Application to Hydroisomerization

Olfa Ben Moussa, Lionel Tinat, Xiaojing Jin, Walid Baaziz, Olivier Durupthy, Celine Sayag, Juliette Blanchard

We successfully prepared bifunctional catalysts with the distance between metallic and acid sites tuned at the nanometer scale. Sols of β-zeolite nanoparticles were synthesized and mixed in optimized conditions with a γ-AlOOH boehmite suspension to yield alumina/zeolite aggregates with a nanometer…

Acidity versus metal-induced Lewis acidity in zeolites for Friedel–Crafts acylation

Claire Bernardon, Manel Ben Osman, Guillaume Laugel, Benoît Louis, Patrick Pale

Acid catalysts including Ni, Ag and Fe-loaded zeolites of different structures were prepared either via cationic exchange or impregnation techniques from pristine H-zeolites (BEA, and MFI). Their catalytic activity was evaluated in the liquid-phase Friedel–Crafts acylation of anisole with propanoic…, Des cations métalliques (Ni, Ag et Fe) ont été incorporés au sein de zéolithes BEA et ZSM-5 par des techniques d'échange cationique et d'imprégnation afin d'obtenir de nouveaux catalyseurs acides solides. Ces matériaux ont ensuite été testés dans une réaction d'acylation de…

Thermal and structural stability of microporous natural clinoptilolite zeolite

Radovan Kukobat, Ranko Škrbić, Pascale Massiani, Karima Baghdad, Franck Launay, Maria Sarno, Claudia Cirillo, Adolfo Senatore, Esad Salčin, Suzana Gotovac Atlagić

Thermal treatment of zeolites prior to their use as adsorbents is needed to remove adsorbed water from zeolite pores, increasing porosity and surface area without inducing structural deterioration. Here, natural zeolite clinoptilolite (CLI) was thermally treated at 378–1073 K in air atmosphere.…

A Graftable Quaternary Ammonium Biocidal Polymer Reduces Biofilm Formation and Ensures Biocompatibility of Medical Devices

Houssam Bouloussa, Azzam Saleh‐mghir, Claire Valotteau, Chahrazad Cherifi, Narjès Hafsia, Martine Cohen‐solal, Charles Court, Anne‐claude Crémieux, Vincent Humblot

A quaternized polyvinylpyridine (Q‐PVP) polymer methanolic solution synthesized in a single step is used to covalently graft titanium surfaces. Q‐PVP is quaternized with varying N+/N ratios. 1 cm2 pure titanium plates are polished and activated. Treated samples are grafted by spin coating or dip‐…

Unraveling the Mechanisms of Hypertrophy-Induced Matrix Mineralization and Modifications in Articular Chondrocytes

Ilhem Lilia Jaabar, Brittany Foley, Alberto Mezzetti, Françoise Pillier, Francis Berenbaum, Jessem Landoulsi, Xavier Houard

Chondrocyte hypertrophic differentiation is a main event leading to articular cartilage degradation in osteoarthritis. It is associated with matrix remodeling and mineralization, the dynamics of which is not well characterized during chondrocyte hypertrophic differentiation in articular cartilage.…

Metallomics in deep time and the influence of ocean chemistry on the metabolic landscapes of Earth's earliest ecosystems

Keyron Hickman-Lewis, Barbara Cavalazzi, Stéphanie Sorieul, Pascale Gautret, Frédéric Foucher, Martin Whitehouse, Heejin Jeon, Thomas Georgelin, Charles Cockell, Frances Westall

Modern biological dependency on trace elements is proposed to be a consequence of their enrichment in the habitats of early life together with Earth's evolving physicochemical conditions; the resulting metallic biological complement is termed the metallome. Herein, we detail a protocol for…
