A simple thermodynamic approach to predict responses from polymer-coated quartz crystal microbalance sensors exposed to organic vapors.

P. Palmas, J. Klingenfus, A. Vedeau, E. Girard, P. Montméat, L. Hairault, C.M. Pradier, C. Methivier

As of lately, the demand for developing artificial sensors with improved capabilities for the detection of explosives, toxics or drugs has increased. Ideally, sensor devices should provide high sensitivity and give a response that is specific to a given target molecule without being influenced by…

Au/xCeO(2)/Al2O3 catalysts for VOC elimination: oxidation of 2-propanol

P. Lakshmanan, L. Delannoy, C. Louis, N. Bion, J.M. Tatibouet

2- Propanol oxidation (1 mol% in air) was investigated over 1% Au/CeO2, 1% Au/Al2O3 and 1% Au/xCeO(2)/Al2O3 (x = 1.5, 3, 5 and 10 wt%) catalysts and the corresponding pure supports. The effects of the catalyst activation procedure (calcination or reduction), cerium oxide morphology and loading, the…

Improved activity and stability in CO oxidation of bimetallic Au-Cu/TiO2 catalysts prepared by deposition-precipitation with urea

A. Sandoval, Catherine Louis, Rodolfo Zanello

Au-Cu bimetallic catalysts supported on TiO2 were prepared for the first time by sequential deposition-precipitation with the urea method, copper first then gold. Au-Cu catalysts with four different Au:Cu atomic ratios were synthesized (1:0.4 to 1:1.2). This method allowed quantitative deposition…

Interaction of ZnII porphyrin with TiO2 nanoparticles: from mechanism to synthesis of hybrid nanomaterials.

Jolanda Spadavecchia, Christophe Méthivier, Jessem Landoulsi, Claire-Marie Pradier

The mechanism of interaction of Zn porphyrin (ZnPP) with TiO2 surfaces is investigated with a view to optimizing the synthesis of hybrid nanomaterials. The strategy consists of studying the adsorption of ZnPP on TiO2 flat surfaces by taking advantage of complementary surface characterization…

Aerobic oxidation of alcohols using ruthenium supported on DD3 kaolin

B. Zadam, D. Obaid, A. Mayoufi, P. Beaunier, F. Launay, F. El Berrichi

Supported ruthenium nanoparticles were prepared through the chemical reduction of aqueous Ru(III) species previously loaded (1 or 5 wt%) onto DD3 kaolin through an ion-exchanged pathway. Resulting nanoporous materials were characterized by XRF, XRD, TEM, EDX, and N2 sorption measurements, and then…

Surface-induced assembly of sophorolipids

Jessie Peyre, Ahmed Hamraoui, Marco Faustini, Vincent Humblot, Niki Baccile

The surface self-assembly properties of acidic sophorolipids, a bolaform microbial glycolipids with pH-responsive properties in solution, were studied based on the chemical nature of the support and pH of the solution. Sophorolipids generally form micelles in water but formation of morphologies…

Hydrolysis of Ammonia-Borane over Ni/ZIF-8 Nanocatalyst: High Efficiency, Mechanism, and Controlled Hydrogen Release

Changlong Wang, Jimena Tuninetti, Zhao Wang, Chen Zhang, Roberto Ciganda, Lionel Salmon, Sergio Moya, Jaime Ruiz, Didier Astruc

Non-noble metal nanoparticles are notoriously difficult to prepare and stabilize with appropriate,dispersion, which in ttirn severely limits their catalytic functions. Here, using zeolitic imidazolate framework (ZIF-8) as MOF template, catalytically remarkably- efficient, ligand-free first-row late…
