In Situ Generation of Active Pd Nanoparticles within a Macroreticular Acidic Resin: Efficient Catalyst for the Direct Synthesis of Hydrogen Peroxide

Kohsuke Mori, Akihiro Hanafusa, Michel Che, Hiromi Yamashita

An acidic resin bearing SO3H functional groups within its reticular structure acts as an efficient support for the in situ formation of highly active Pd nanoparticles (NPs) responsible for the direct synthesis of hydrogen peroxide from H2 and O2. Characterization by means of X-ray absorption fine…

Quantitative Investigation of MgO Bronsted Basicity: DFT, IR, and Calorimetry Study of Methanol Adsorption

Hugo Petitjean, Konstantin Tarasov, Francoise Delbecq, Philippe Sautet, Jean-Marc Krafft, Philippe Bazin, Maria Cristina Paganini, Elio Giamello, Michel Che, Helene Lauron-Pernot, Guylene Costentin

The adsorption geometries, energies, and vibrational frequencies of methanol on MgO defective surfaces have been calcd. by periodic DFT simulations. The results are very comparable with those obtained with water and are also in very good accordance with microcalorimetry and IR expts. At low…

On the radical cracking of n-propylbenzene to ethylbenzene or toluene over Sn/Al2O3-Cl catalysts under reforming conditions

S Toppi, C Thomas, C Sayag, D Brodzki, Katia Fajerwerg, F Lepeltier, C Travers, G Djegamariadassou

Two series of chlorided-alumina-supported Sn catalysts were synthesized with different precursors, SnCl2 or SnBu4, and with various contents of Sn. The acidity of the catalysts including 0.2 wt% Sn was characterized by FTIR adsorption–desorption of 2,6-dimethylpyridine (Brønsted acidity) and…

On the chemistry of the conversion coatings

Oumaïma Gharbi, Kevin Ogle, Junsoo Han

A conversion coating is an inorganic or organic–inorganic hybrid surface film conveying specific desirable functions to a material, formed by a spontaneous reaction between the material and an electrolyte. This chapter reviews the fundamental physical chemistry of the conversion coating process and…

Hydrogen and syngas production by methane dry reforming on SBA-15 supported nickel catalysts: On the effect of promotion by Ce0.75Zr0.25O2 mixed oxide

Abdulkader Albarazi, Patricia Beaunier, Patrick da Costa

In this work, the effects of doping Ni-based SBA-15 catalysts with Ceria-Zirconia mixed oxide (CZ) on the activity and stability of these catalysts during syngas production by methane dry reforming (MDR) were investigated and compared with the activity and stability of unmodified Ni/SBA-15. The…

Evidence for emission and transfer of energy from excited edge sites of MgO smokes by photoluminescence experiments.

Romain Hacquart, Jean-Marc Krafft, Guylène Costentin, Jacques Jupille

New features are observed in photoluminescence spectra of MgO smokes produced in controlled conditions, an experiment inspired by previous measurements on cleaved MgO(100). Upon photoexcitation at 5.17–5.45 eV, most luminescence spectra observed can be decomposed into two bands, peaking at 3.82–3.…

The properties of nickel-tungsten sulfide supported on MCM-41 aluminosilicate materials assembled from beta-zeolite seeds ([beta]-MCM-41) were examined in the conversion of 4,6-dimethyldibenzothiophene (4,6-DMDBT) pure or in mixture with dimethyldisulfide, carbazole and tetralin. As reported in the…
