Optimization of Synthesis Conditions of Ni/SBA-15 Catalysts: Confined Nanoparticles and Improved Stability in Dry Reforming of Methane

Nissrine El Hassan, Marie-Nour Kaydouh, Nissrine El, Anne Davidson, Pascale Massiani

Despite its economic and environmental advantages, the dry reforming of methane using supported Ni-based catalysts remains challenging due to problems of metal particle sintering and carbon deposition, which lead to loss in catalytic activity. In this study, different silica supports, containing 5…

On the origin of the changes in color of Ag/Al2O3 catalysts during storage

Tesnim Chaieb, Dalil Brouri, Sandra Casale, Jean-Marc Krafft, Tiago da Silva, Cyril Thomas, Laurent Delannoy, Catherine Louis

Despite the large number of catalytic studies involving Ag/Al2O3 catalysts, especially in deNOx reactions, the phenomenon of ageing observed during catalysts storage after preparation by impregnation followed by a calcination treatment, has not been reported earlier and rises questions. The present…

Electron conductive self-assembled hybrid low-molecular weight glycolipid-nanosilver gels

Korin Gasia Ozkaya, Othmane Darouich, Hynd Remita, Isabelle Lampre, Lionel Porcar, Alain Carvalho, M. Schmutz, Sandra Casale, Christel Laberty-Robert, Niki Baccile

Low-molecular weight (LMW) hydrogels are gaining interest over macromolecular gels due to their reversible, dynamic and stimuli-responsive nature. They are potentially interesting functional materials for advanced applications such as catalysis, nanoelectronics or regenerative medicine. One common…

An EPR characterisation of stable and transient reactive oxygen species formed under radiative and non-radiative conditions

E. Richards, D. M Murphy, M. Che

Electron paramagnetic resonance (EPR) spectroscopy is the ideal method of choice when detecting and studying the wide variety of paramagnetic oxygen-centred radicals. For simple diatomic radicals, such as the superoxide (O 2 −) or peroxy (ROO •) species, the CW EPR profile (in particular the g-…

Permanently hydrophilic, piezoelectric PVDF nanofibrous scaffolds promoting unaided electromechanical stimulation on osteoblasts

Maria Kitsara, Andreu Blanquer, Gonzalo Murillo, Vincent Humblot, Sara de Bragança Vieira, Carme Nogués, Elena Ibáñez, Jaume Esteve, Leonardo Barrios

Biomimetic functional scaffolds for tissue engineering should fulfil specific requirements concerning structural, biochemical and electro-mechanical characteristics, depending on the tissue that they are designed to resemble. In bone tissue engineering, piezoelectric materials based on poly(…

Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…

Heterogeneous catalytic partial oxidation of lower alkanes (C 1 –C 6 ) on mixed metal oxides

Jacques Védrine

This review paper aims at analysing the state of the art for partial oxidation and oxidative dehydrogenation (ODH) reactions of lower alkanes C1–C6 into olefins and oxygenated products (aldehydes, anhydrides, carboxylic acids) on metal oxide catalysts with cations of variable oxidation state, such…

Ni/CeO2 Nanoparticles Promoted by Yttrium Doping as Catalysts for CO2 Methanation

Valeria La Parola, Chao Sun, Patricia Beaunier, Leonarda F Liotta, Patrick da Costa

Ni (5 wt.%) catalysts over yttrium modified CeO2 oxides synthesized by hydrothermal method were prepared. For comparison Ni was supported over pure CeO2 and Y2O3. Characterizations by N2 adsorption/desorption, XRD, XPS, TEM/HRTEM, H2-TPR, CO2-TPD and TGA were carried out. The catalytic performance…

Nanosized Layered TOT Magnesium-Silicates: Equilibrium Morphologies and Surface Speciation, a Computational and Experimental Study

Hervé Toulhoat, Longfei Lin, Dalil Brouri, Jean-Marc Krafft, Yannick Millot, Guillaume Laugel, Hélène Lauron-Pernot

The morphology, surface speciation, NMR, and IR spectroscopic properties of nanosized layered magnesium silicate isostructural to talc at equilibrium in an aqueous environment were computed from first principles. The theoretical predictions were successfully compared with experimental results…
