Mesoporous nickel-alumina catalysts derived from MIL-53(Al) metal-organic framework: A new promising path for synthesizing CO2 methanation catalysts

Leila Karam, Maria C Bacariza, José M Lopes, Carlos Henriques, Julien Reboul, Nissrine El Hassan, Pascale Massiani

A new synthesis route for the preparation of highly efficient and stable porous Ni-based alumina catalysts for CO2 methanation is presented. It is based on the use of MIL-53(Al), an Al-containing metal-organic framework (MOF) with high surface area, as sacrificial support. A series of Ni-Al2O3…

Selectivity in the gas-phase hydrogenation of 4-nitrobenzaldehyde over supported Au catalysts

Noémie Perret, Xiaodong Wang, Thomas Onfroy, Christophe Calers, Mark A Keane

The effects of Au particle size and support properties have been examined in the gas-phase hydrogenation of 4-nitrobenzaldehyde over Au/ZrO2, Au/TiO2 and Au/Al2O3. Gold particle size was varied using deposition-precipitation and impregnation syntheses. The catalysts have been characterised in terms…

Time-of-Flight Secondary Ion Mass Spectrometry Investigation of the Orientation of Adsorbed Antibodies on SAMs Correlated to Biorecognition Tests

Victor Lebec, Souhir Boujday, Claude Poleunis, Claire-Marie Pradier, Arnaud Delcorte

The adsorption of an antiglutamate dehydrogenase (Anti-GDH) antibody on different surfaces was studied to probe its orientation and bioactivity. Three different situations were investigated: physisorption on a −COOH-terminated thiols self-assembled monolayer (SAM) on gold, covalent grafting on the…

Relantionship between the feedstock powders reactivity and the Electrochemical properties of 316L Stainless steel obtained by laser powder bed fusion

Alexis Fouchereau, Beatriz Puga, Hicham Maskrot, Fernando Lomello, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

3D printing by Laser-Powder Bed Fusion (L-PBF) is an innovative process using a high energy density laser to melt the raw material into a powder form. Previous studies have shown that the powder properties are crucial for the density, quality and microstructure of the materials produced [1, 2] but…

Does the S-H Bond Always Break after Adsorption of an Alkylthiol on Au(111)?

Hazar Guesmi, Noelia B. Luque, Elizabeth Santos, Frederik Tielens

The reaction mechanism for the formation of alkyl thiol self-assembled monolayers (SAM) on Au(111) is still not clearly understood. Especially, the role of defects on the chemisorption process is an important goal to be addressed. In this work, different minimum energy reaction paths for R−SH…

Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

Preparation of Pt°/MCM-41: effect of drying on MCM-41 structure and Pt° dispersion

Baichun Zhu, Franck Letellier, Juliette Blanchard, Katia Fajerwerg, Catherine Louis, Denis Guillaume, Denis Uzio, Miehèle Breysse

Pt°/MCM-41 catalysts were prepared by electrostatic adsorption of Pt(NH3)42+ at pH=8, followed by calcination under O2 and reduction. This procedure allows to prepare highly dispersed Pt° nanoparticles (D>76%), but has the drawback to modify significantly the structure of the ordered mesoporous…
