Influence of Cu on the catalytic activity of FeBEA zeolites in SCR of NO with NH 3

Paweł Boroń, Lucjan Chmielarz, Stanislaw Dzwigaj

Two series of Fe and/or Cu containing BEA zeolites were prepared by different procedures: two-step postsynthesis method (FexSiBEA, CuxSiBEA and FexCuxSiBEA) and conventional wet impregnation (FexHAlBEA, CuxHAlBEA and FexCuxHAlBEA) (x = 1.0 Fe or Cu wt%). Modification of BEA zeolite resulted in the…

Characterization and catalytic activity of Mn (salen) immobilized on silica by various strategies

Khalil Tesnime Abou, Chaaben Semy Ben, Boujday Souhir, Bergaoui Latifa

Different strategies were applied to prepare supported Mn(salen) on fumed silica and to explore the effect of the interaction nature between the active sites and the surface on the catalytic activity. Direct and multistep grafting methods were used: the silica surface was silylated and the metal…

Dispersion and states of platinum ions in BEA-zeolite pores: effect of the framework basicity

C. Bisio, Katia Fajerwerg, J. Krafft, P. Massiani, G. Martra

Pt/Cs-BEA materials prepared by a classical ion-exchange procedure using two Cs-BEA supports with different Cs loadings, and a reference acidic Pt/H-BEA, have been studied to investigate the effect of the framework basicity (evaluated by FT-IR of adsorbed CO2) on the state of platinum species after…

Influence of the grafting process on the orientation and the reactivity of azide-terminated monolayers onto silica surface

Nisreen Al-Hajj, Yannick Mousli, Antoine Miche, Vincent Humblot, Julien Hunel, Karine Heuze, Thierry Buffeteau, Emilie Genin, Luc Vellutini

Click chemistry is widely used in materials and surface science for its high efficiency, ease of use and high yields. Azide-terminated SAMs have been prepared successfully by using three different deposition methods (postfunctionalization and direct grafting by immersion as well as spin coating).…

Bimetallic Ni-Zn/TiO2 catalysts for selective hydrogenation of alkyne and alkadiene impurities from alkenes stream

Zhao Wang, Guillaume Wang, Catherine Louis, Laurent Delannoy

This study investigates the alternative of replacing noble metals by base metals as catalysts for selective hydrogenation of polyunsaturated hydrocarbons. Nickel catalysts are active for this type of reaction, but poorly selective. However, former calculations anticipated that Ni-Zn alloys could…

The concentration of bone-related organic additives drives the pathway of apatite formation

Marc Robin, Camila B Tovani, Jean-Marc Krafft, Guylène Costentin, Thierry Azaïs, Nadine Nassif

Bone models set for studying apatite mineralization tend to use excess of organic additives and a very low concentration of collagen in the light of those described in the biological tissue. However, the activity of soluble additives during mineral deposition is highly dependent on their…

Silk foams with metallic nanoparticles as scaffolds for soft tissue regeneration

Claire de Lartigue, Cristina Belda Marín, Vincent Fitzpatrick, Antonella Esposito, Sandra Casale, Jessem Landoulsi, Erwan Guénin, Christophe Egles

Tissue regeneration can be achieved by providing endogenous cells with a biomaterial scaffold that supports their adhesion and proliferation, as well as the synthesis and deposition of an extracellular matrix (ECM). In this work, silk fibroin protein foams were formed by lyophilization to generate…
