DFT study of the M segregation on MAu alloys (M = Ni, Pd, Pt) in presence of adsorbed oxygen O and O2

Adnene Dhouib, Hazar Guesmi

Segregation phenomena of group 10 (M = Ni, Pd, Pt) transition-metals substituted in Au (1 1 1) surface and sub-surface layers are investigated by DFT periodic calculations in presence of adsorbed atomic and molecular oxygen. In contrast with vacuum conditions, where the metal impurities M prefer to…

Formation of heteropolymolybdates during the preparation of Mo and NiMo HDS catalysts supported on SBA-15: Influence on the dispersion of the active phase and on the HDS activity

Alvaro Sampieri, Stephane Pronier, Sylvette Brunet, Xavier Carrier, Catherine Louis, Juliette Blanchard, Katia Fajerwerg, Michele Breysse

Mo and Ni-Mo sulfides in SBA-15 and Al-SBA-15 catalysts were prepd. by incipient wetness co-impregnation of molybdenum and nickel precursors (followed by thermal treatment under He at 823 K) and sulfidation under 10% H2S/H2 at 673 K. Only incipient wetness impregnation of Mo on pure silica SBA-15…

Heterometallic and Hydrophobic Metal–Organic Frameworks as Durable Photocatalysts for Boosting Hydrogen Peroxide Production in a Two-Phase System

Xiaolang Chen, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

Reductive production of hydrogen peroxide (H2O2) from dioxygen (O2) coupled with the oxidative synthesis of value-added products using hydrophobic metal–organic frameworks (MOFs) is very important for energy production. Herein, a hydrophobic iron-doped zirconium-based MOF (OPA/Fe-Zr-MOF), in which…

Identification of cationic and oxidic caesium species in basic Cs-overloaded BEA zeolites

Pascale Massiani, C. Bisio, Katia Fajerwerg, L. Sordelli, L. Stievano, E.R. Silva, S. Coluccia, G. Martra

A parent acidic H-BEA with crystallites very small in size and high external surface area was used to prepare a series of materials loaded with increasing Cs+ contents by firstly ion-exchange and then impregnation with CsOH solutions. The monitoring of the ion- exchange process by chemical analysis…
