No particle size effects in the electrochemical conversion of Co2 to formate on Sn electrodes

Carlos M Sánchez-Sánchez, A. Del Castillo, Manuel Alvarez-Guerra, Juliette Blanchard, A. Irabien

Recycling of CO2 emissions by direct electrocatalytic reduction of CO2 has been pointed out as a feasible method for CO2 conversion into useful chemical products and fuels. In particular, formic acid (HCOOH) represents one of the most interesting products obtained, since HCOOH is widely used in…

On the radical cracking of n-propylbenzene to ethylbenzene or toluene over Sn/Al2O3-Cl catalysts under reforming conditions

S Toppi, C Thomas, C Sayag, D Brodzki, Katia Fajerwerg, F Lepeltier, C Travers, G Djegamariadassou

Two series of chlorided-alumina-supported Sn catalysts were synthesized with different precursors, SnCl2 or SnBu4, and with various contents of Sn. The acidity of the catalysts including 0.2 wt% Sn was characterized by FTIR adsorption–desorption of 2,6-dimethylpyridine (Brønsted acidity) and…

Investigation of co-hosted basic and metal nanoparticles in Pt/Cs-BEA zeolites

C. Bisio, Katia Fajerwerg, G. Martra, P. Massiani

Various acido-basic BEA zeolites having different Cs contents and containing supported Pt particles were prepared using two acidic parent BEA supports with same framework Al content but with strongly different morphology of the zeolite crystallites. In spite of highly different exchange capacities…

Basic Cs-Pt/MCM-41 Catalysts: Synthesis, Characterization and Activity in n-Hexane Conversion

J. Blanchard, Katia Fajerwerg, M. Breysse, P. Beaunier, M.F. Ribeiro, J.M. Silva, P. Massiani

Cs-Pt/MCM-41 catalysts with basic character have been prepared by selective adsorption of Pt(NH3)4(OH)2 at pH = 8 on pure silica MCM-41 followed by incipient-wetness impregnation of CsNO3, then oxidation and reduction. The influence of the amount of Cs (0, 2 and 4 wt%) on the size of the reduced Pt…

Monitoring by in situ neutron diffraction of simultaneous dehydration and Ni2+ mobility in partially exchanged NaY zeolites

Florence Porcher, Jean-Louis Paillaud, Lucia Gaberova, Gilles André, Sandra Casale, Pascale Massiani

Powder neutron diffraction is used to follow structural changes occurring during heat and vacuum assisted dehydration of 3 wt% nickel exchanged NaY. The structures determined from Rietveld refinement confirm the nickel ion displacement from the supercages and sodalite cages towards hexagonal prisms…

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…

Plasmonic Properties of Gold Nanostructures on Gold Film

Médéric Lequeux, David Mele, Priyamvada Venugopalan, Raymond Gillibert, Souhir Boujday, Wolfgang Knoll, Jakub Dostalek, Marc Lamy de La Chapelle

This paper reports on a systematic study of the plasmonic properties of periodic arrays of gold cylindrical nanoparticles in contact with a gold thin film. Depending on the gold film thickness, it observes several plasmon bands. Using a simple analytical model, it is able to assign all these modes…
