Anchoring of Pt(II) Pyridyl Complex to Mesoporous Silica Materials: Enhanced Photoluminescence Emission at Room Temperature and Photooxidation Activity using Molecular Oxygen

Kohsuke Mori, Kentaro Watanabe, Masayoshi Kawashima, Michel Che, Hiromi Yamashita

Chloro(2,2':6',2''-terpyridine)platinum(II) ([Pt(tpy)Cl]Cl) complex was successfully anchored to a series of (3-aminopropyl)trimethoxysilane-modified mesoporous silica materials (MCM-41, SBA-15, and MCM-48). Pt LIII-edge x-ray absorption fine structure (XAFS) measurements reveal…

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…

Incorporation of Mn into the vacant T-atom sites of a BEA zeolite as isolated, mononuclear Mn: FTIR, XPS, EPR and DR UV-Vis studies

R. Baran, L. Valentin, Stanislaw Dzwigaj

A MnSiBEA zeolite has been prepared via a two-step postsynthesis procedure which consisted, in the first step, of the treatment of a tetraethylammonium BEA zeolite with nitric acid for the formation of vacant T-atom sites and then, in the second step, of the incorporation of Mn ions into the…

Role of Hydroxyl Groups in the Basic Reactivity of MgO : a Theoretical and Experimental Study

Céline Chizallet, Guylène Costentin, Hélène Lauron-Pernot, Jean Marc Krafft, Philippe Bazin, Jacques Saussey, Françoise Delbecq, Philippe Sautet, Michel Che

Clean (i.e., carbonate- and hydroxyl-free) and hydroxylated MgO surfaces of various morphologies were used to study the correlation between thermodynamic Brønsted basicity (evaluated by the deprotonation of methanol and propyne followed by FTIR) and basic reactivity (evaluated by the conversion of…

Biocidal Properties of a Glycosylated Surface: Sophorolipids on Au(111)

Claire Valotteau, Christophe Calers, Sandra Casale, Jan Berton, Christian V. Stevens, Florence Babonneau, Claire-Marie Pradier, Vincent Humblot, Niki Baccile

Classical antibacterial surfaces usually involve antiadhesive and/or biocidal strategies. Glycosylated surfaces are usually used to prevent biofilm formation via antiadhesive mechanisms. We report here the first example of a glycosylated surface with biocidal properties created by the covalent…

Porous nickel-alumina derived from metal-organic framework (MIL-53): a new approach to achieve active and stable catalysts in methane dry reforming

Leila Karam, Julien Reboul, Sandra Casale, Pascale Massiani, Nissrine El Hassan

An Al‐containing MIL‐53 metal‐organic framework with very high surface area (SBET=1130 m2.g−1, N2 sorption) was used as sacrificial template to prepare a nickel‐alumina‐based catalyst (Ni0AlMIL) highly active and stable in the reaction of dry reforming of methane (DRM). The procedure consisted in…

Gold Colloid-Nanostructured Surfaces for Enhanced Piezoelectric Immunosensing of Staphylococcal Enterotoxin A

Maroua Ben Haddada, Michèle Salmain, Souhir Boujday

We describe the use of gold nanoparticles (AuNP) as a nanostructuring agent on quartz crystal sensor chips to engineer staphylococcal enterotoxin A (SEA) piezoelectric biosensors with amplified response. AuNPs were assembled on gold- or silicon-coated quartz crystal sensor chips by a wet chemistry…

We demonstrate a high electron conductivity (> 10^2 S/cm and up to 10^3 S/cm) of tungsten suboxide W18O(52.4-52.9)(or equivalently WO(2.91-2.94)) nanotubes (2 to 3 nm in diameter, ca. micrometer long). The conductivity is measured in the temperature range 120 to 300K by a four probe scanning…

Mueller micropolarimeter for color imaging of aluminium metasurfaces

M. Nicolas, I. Soumahoro, L. Zhang, G. Guida, W. Daney de Marcillac, D. Demaille, C. Schwob, S. Boujday, Bruno Gallas

Many anticounterfeiting tags rely on images intricate in different color and/or different polarization states to create optical effects invisible in conventional observation conditions. We build here an imaging micropolarimeter based on the dual rotating compensator system and using the color…
