Compared activity and stability of three Ni-silica catalysts for methane bi- and dry reforming

Karam Jabbour, M.N. Kaydouh, N El Hassan, H El Zakhem, Sandra Casale, Anne Davidson, Pascale Massiani

A low weight % of Ni (5 wt %) and the two solvents technique of deposition are used to obtain well-dispersed Ni-species (either particles or species dispersed on the silica surface) and avoid the formation of large particles on three silicas SBA-15, Aerosil 300 and diatoms MN3. Stability tests at…

Bimetallic Au-Ag/TiO2 catalyst prepared by deposition-precipitation: High activity and stability in CO oxidation

A. Sandoval, A. Aguilar, C. Louis, Agnes Traverse, Rodolfo Zanella

Au-Ag bimetallic catalysts supported on TiO2 were prepared by sequential deposition-precipitation method, silver first and then gold. Au-Ag catalysts with different Au/Ag atomic ratios were synthesized. XANES and H2 TPR results show that gold is more easily reduced in bimetallic catalysts than in…

Hierarchical Self-Assembly of Polyoxometalate-Based Hybrids Driven by Metal Coordination and Electrostatic Interactions: From Discrete Supramolecular Species to Dense Monodisperse Nanoparticles

Guillaume Izzet, Benjamin Abécassis, Dalil Brouri, Madeleine Piot, Benjamin Matt, Stefano Artin Serapian, Carles Bo, Anna Proust

The metal-driven self-assembly processes of a covalent polyoxometalate (POM)-based hybrid bearing remote terpyridine binding sites have been investigated. In a strongly dissociating solvent, a discrete metallomacrocycle, described as a molecular triangle, is formed and characterized by 2D diffusion…

Heteropolytungstate-decorated core-shell magnetic nanoparticles: A covalent strategy for polyoxometalate-based hybrid nanomaterials

Ourania Makrygenni, Emilie Secret, Aude Michel, Dalil Brouri, Vincent Dupuis, Anna Proust, Jean-Michel Siaugue, Richard Villanneau

Amino-functionalized core-shell magnetic nanoparticles have been covalently grafted with Polyoxometalates (POMs). These multifunctional nanocomposites have been obtained through the coupling of heteropolytungstate-based hybrids bearing carboxylic acid functions with aminopropyl functions that…
