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…

Surface chemistry and surface reactivity of fibrous amphiboles that are not regulated as asbestos

M. Fantauzzi, M. Pacella, J. Fournier, A. Gianfagna, G. B. Andreozzi, A. Rossi

Three fibrous amphiboles that are not regulated as asbestos--two from Biancavilla (Sicily, Italy) and one from Libby (MT, USA)--were studied in order to establish relationships between surface chemistry and surface reactivity. The three fibrous samples, plus one prismatic fluoro-edenite from…

The synergistic power of theory and experiment in the field of catalysis

Frederik Tielens, Monica Calatayud

Potential energy curves, equilibrium interatomic distances, term energies and harmonic vibration frequencies for the 16 lowest states of neutral carbon monoxide and the six lowest states of singly ionized carbon monoxide are calculated by density functional theory (DFT) and linear-response time-…

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…

Effect of nanocrystallization on the structure and the magnetic properties of Nd–Fe–Co–Al–B glassy alloy

Lotfi Bessais, C. Djéga-Mariadassou, P. Beaunier

Nd 40 Fe 30 Co 15 Al 10 B 5 bulk amorphous prepared by high energy milling shows a coercivity of 650kA∕m with a Curie temperature of 645K. The controlled nanocrystallization enhances the coercivity to 1600kA∕m and the remanence ratio is equal to 0.59. The coexistence of two crystalline magnetic…

One-pot synthesis of a new generation of hybrid bisphosphonate polyoxometalate gold nanoparticles as antibiofilm agents

S. Tomane, E. López-Maya, S. Boujday, V. Humblot, J. Marrot, N. Rabasso, J. Castells-Gil, C. Sicard, Anne Dolbecq, P. Mialane, A Vallée

A reduced polyoxovanadate functionalized with bisphosphonate molecules was synthesized and used to prepare in one step hybrid organic-inorganic polyoxometalate decorated gold nanoparticles. These new composites were shown to strongly inhibit P. aeruginosa and S. epidermidis biofilms growth, the…

Solvent effects on the vibrational spectrum of 3-hydroxyflavone

Ari Paavo Seitsonen, Abdenacer Idrissi, Stefano Protti, Alberto Mezzetti

3-hydroxyflavone (3HF) is a widely studied molecule that acts as a simplified prototype of biological, more complex flavonoids. Its solvation mechanism is still under investigation. Here we report a joint experimental and simulation study of the vibrational properties of 3HF in gas phase and in…

A new method for elaborating mesoporous SiO 2 /montmorillonite composite materials

Khalil Tesnime Abou, Chaabene Semy Ben, Boujday Souhir, Blanchard Juliette, Bergaoui Latifa

We report the sol–gel preparation of SiO 2 / montmorillonite composite materials and the investigation of the effect of the amount of clay and the TEOS concentration on the textural and structural properties of the composites. Pre-swelling of the clay with cetyltrimethyl ammonium results in solids…
