Recent studies on the preparation, activation and design of active phases and supports of hydrotreating catalysts

Michèle Breysse, C. Geantet, P. Afanasiev, Juliette Blanchard, M. Vrinat

Commercial hydrotreating catalysts are usually composed of a sulfide active phase, molybdenum or tungsten sulfide promoted by cobalt or nickel, supported on alumina. Due to very stringent environmental regulations, the research effort to enhance the properties of these catalysts is still very…

Impact of sorbitol addition on the structure and performance of silica-supported cobalt catalysts for Fischer-Tropsch synthesis

Hong Jingping, Eric Marceau, Andrei Y. Khodakov, Anne Griboval-Constant, Camille La Fontaine, Françoise Villain, Valérie Briois, P.A. Chernavskii

The paper focuses on the impact of sorbitol addition on the genesis of cobalt active phases in silica-supported catalysts and on their performance in Fischer-Tropsch synthesis. The catalysts were characterized by ex situ and in situ diffuse reflectance spectroscopy in the ultraviolet and visible…

Hybrid Hydrophobin/Gold Nanoparticles: Synthesis and Characterization of New Synthetic Probes for Biological Applications

Jane Politi, Luca de Stefano, Paola Giardina, Sandra Casale, Ilaria Rea, Jolanda Spadavecchia

We report a simple and original method to synthesize gold nanoparticles in which a fungal protein, the hydrophobin Vmh2 from Pleurotus ostreatus, mixed to cetyltetrammonium bromide (CTAB) has been used as additional component in a one-step synthesis, leading to shell-like hybrid protein-metal…

Genesis of supported carbon-coated Co nanoparticles with controlled magnetic properties, prepared by decomposition of chelate complexes

Konstantin Tarasov, Patricia Beaunier, Michel Che, Eric Marceau, Yanling Li

Following procedures formerly developed for the prepn. of supported heterogeneous catalysts, carbon-coated cobalt nanoparticles dispersed on porous alumina have been prepd. by impregnation of γ-Al2O3 with (NH4)2[Co(EDTA)] and thermal decompn. in inert atm. Below 350 °C, Co(II) ions are complexed…

Mechanism and deactivation process of the conversion of methylbutynol on basic faujasite monitored by operando DRIFTS

Jean-Francois Groust, Guylene Costentin, Jean-Marc Krafft, Pascale Massiani

The successive steps occurring during conversion of methylbutynol (MBOH) on a basic NaX zeolite catalyst were characterized by combined micro-GC and operando DRIFT spectroscopy, assocd. to TPD-MS expts. These techniques permit to reveal a very strong and fast initial decrease in MBOH consumption,…

Mesostructured or Alumina-mesostructured Silica SBA-16 as Potential Support for NOx Reduction and Ethanol Oxidation

Maya Boutros, Thomas Onfroy, Patrick da Costa

Synthesis of some meso-structured SiO2 or aluminosilica (SBA-16 and Al-SBA-16) with a 3-dimensional cubic structure is reported. Structural and porosity properties of these materials were studied by x-ray diffraction, N2 sorption, and transmission electron microscopy imaging.; Al insertion was detd…

Surface IR immunosensors for label-free detection of benzo[a]pyrene

Souhir Boujday, Soumaya Nasri, Michele Salmain, Claire-Marie Pradier

Polycyclic aromatic hydrocarbons (PAHs) are a family of contaminants originating from the incomplete combustion of organic compounds, present in the urban air, water, soil and also foodstuff. Due to their recognised carcinogenicity, their concentration in urban air is routinely monitored and…

Influence of the texturalproperties of porousaluminas on the reducibility of Ni/Al2O3 catalysts

Faiza Bentaleb, Eric Marceau

Temperature-programmed reduction (TPR) profiles recorded on calcined Ni/Al2O3 catalysts exhibiting the same Ni(II) surface density (3 Ni2+ nm−2) suggest that nickel speciation and reducibility are significantly influenced by the specific surface area and texturalproperties of aluminas, and by their…
