Clicked BODIPY‐Fullerene‐Peptide Assemblies: Studies of Electron Transfer Processes in Self‐Assembled Monolayers on Gold Surfaces

Jad Rabah, Houssein Nasrallah, Karen Wright, Isabelle Gérard, Hélène Fensterbank, Thi Tuyet Van Bui, Jérôme Marrot, Thu-Trang Tran, Anam Fatima, Minh-Huong Ha-Thi, Rachel Méallet, Gotard Burdzinski, Gilles Clavier, Souhir Boujday, Hubert Cachet, Catherine Debiemme-Chouvy, Emmanuel Maisonhaute, Anne Vallée, Emmanuel Allard

Two BODIPY‐C60‐peptide assemblies were synthesized by CuAAC reactions of BODIPY‐C60 dyads and a helical peptide functionalized with a terminal alkyne group and an azide group, respectively. The helical peptide within these assemblies was functionalized at its other end by a disulfide group,…

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…

Search for confinement effects in mesoporous supports: hydrogenation of o-xylene on Pt /MCM-41

Franck Letellier, Juliette Blanchard, Katia Fajerwerg, Catherine Louis, Michele Breysse, Denis Guillaume, Denis Uzio

The occurrence in meso-porous supports of a confinement effect related to the adsorption strength of a reaction intermediate on a metallic phase dispersed in the meso pores is examd., as well as its effect on the activity and selectivity. A model is proposed in order to det. the catalyst…

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…

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…

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,…

High-Current-Density CO2-to-CO Electroreduction on Ag-Alloyed Zn Dendrites at Elevated Pressure

Sarah Lamaison, David Wakerley, Juliette Blanchard, David Montero, Gwenaelle Rousse, Dimitri Mercier, Philippe Marcus, Dario Taverna, Domitille Giaume, Victor Mougel, Marc Fontecave

High-surface-area Ag-Zn-alloyed electrodes undertake the rapid conversion of CO 2 to CO. This has the combined benefit of removing CO 2 and producing an industrially relevant chemical synthon. At atmospheric pressure, the electrodes plateau in activity owing to the mass-transport limitation of CO 2…
