Effect of dealumination on the catalytic performance of Cr-containing Beta zeolite in carbon dioxide assisted propane dehydrogenation

Piotr Michorczyk, Kamila Zeńczak-Tomera, Barbara Michorczyk, Adam Węgrzyniak, Marcelina Basta, Yannick Millot, Laetitia Valentin, Stanislaw Dzwigaj

New active and selective catalysts for propane to propene dehydrogenation in assistance of CO 2 (CO 2-PDH) were prepared by chromium incorporation in siliceous SiBeta. The Cr-containing SiBeta zeolite catalysts were obtained by two-step postsynthesis preparation procedure which consist, in the…

Effect of pore geometry of mesoporous supports on catalytic performances in methane reforming

Joy Tannous, Leila Karam, Marie-Nour Kaydouh, Henri El Zakhem, Nissrine El Hassan, Sandra Casale

Catalysts prepared using three dimensional SBA-16 silica support (composed of micropores and cage-like mesopores) were tested in the reaction of methane dry reforming, in comparison with 2D hexagonal mesoporous SBA-15 support. The samples were evaluated by N 2 sorption and X-Ray diffraction (XRD)…

CO2 valorization using epoxides under mild conditions

Viviana Contreras Moreno, Lionel Estel, Laurent Bischoff, Vincent Levacher, Marie-Pierre Denieul, Alain Ledoux, Salim Derrouiche

Carbon dioxide is the major greenhouse gas suspected to produce the climatic change. In order to reduce the emissions of CO 2 , several ways have been studied like capture process, geological storage and valorization. Recently one of the most important studies is concentrated on chemical…

Influence of organic additives on the properties of impregnationsolutions and on nickel oxide particle size for Ni/Al2O3catalysts

Faiza Bentaleb, Michel Che, Anne-Claire Dubreuil, Cécile Thomazeau, Eric Marceau

tThe introduction of organic additives, such as polyols, sugars or polyacids, in impregnation solutionshas been suggested to better control the size of nanoparticles on supported catalysts. The present paperfocuses on the roles played by three of these additives, sorbitol, glucose and citric acid,…

Antibacterial properties of sophorolipid-modified gold surfaces against Gram positive and Gram negative pathogens

Claire Valotteau, Ibrahim M. Banat, Christopher A. Mitchell, Helen Lydon, Roger Marchant, Florence Babonneau, Claire-Marie Pradier, Niki Baccile, Vincent Humblot

Sophorolipids are bioderived glycolipids displaying interesting antimicrobial properties. We show that they can be used to develop biocidal monolayers against Listeria ivanovii, a Gram-positive bacterium. The present work points out the dependence between the surface density and the antibacterial…

Surface plasmon resonance: signal amplification using colloidal gold nanoparticles for enhanced sensitivity

Sabine Szunerits, Jolanda Spadavecchia, Rabah Boukherroub

Among all the detection methods developed for bioassays, optical-based approaches are the most popular techniques. A widely used and accepted bioanalytical technique for routine characterization of molecular recognition events at a solid interface is surface plasmon resonance (SPR) spectroscopy.…
