Preparation of amorphous silica-aluminas with enhanced acidic properties and spectroscopic identification of their acid sites, Préparation de silice-alumines amorphes avec des propriétés acides améliorées et identification spectroscopique de leurs sites acides

Xiaojing Jin

ASAs with enhanced acidity and a higher fraction of acidic Al were prepared by two experimental strategies. Their textures have been investigated by N2 adsorption–desorption and their acidic properties by FTIR of adsorbed probe molecule (pyridine or CO). Besides, isomerization of 33DMB1 was…, Des silice-alumines (SA) avec des propriétés acides améliorées et une fraction plus élevée d’aluminium acides ont été préparées en utilisant deux stratégies de synthèse. Leurs propriétés texturales ont été étudiées par physisorption de N2 et leurs propriétés acides par suivi FTIR de l’adsorption de…

Tuning Model Drug Release and Soft-Tissue Bioadhesion of Polyester Films by Plasma Post-Treatment

Vishal T. Mogal, Chaw Su Yin, Richard O’rorke, Souhir Boujday, Christophe Méthivier, Subbu S. Venkatraman, Terry W. J. Steele

lasma treatments are investigated as a post-production method of tuning drug release and bioadhesion of poly(lactic-co-glycolic acid) (PLGA) thin films. PLGA films were treated under varying conditions by controlling gas flow rate, composition, treatment time, and radio frequency (RF) power. In…

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…

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…

Ultra-Compact Electrical Double Layers at TiO₂ (110) Electrified Interfaces

Immad Nadeem, Christopher Penschke, Ji Chen, Xavier Torrelles, Axel Wilson, Hadeel Hussain, Gregory Cabailh, Oier Bikondoa, Jameel Imran, Christopher Nicklin, Robert Lindsay, Jörg Zegenhagen, Matthew Blunt, Angelos Michaelides, Geoff Thornton

Metal-oxide aqueous interfaces are important in areas as varied as photocatalysis and mineral reforming. Crucial to the chemistry at these interfaces is the structure of the electrical double layer formed when anions or cations compensate for the charge arising from adsorbed H<sup>+</sup…
