PdAg alloy nanoparticles encapsulated in N-doped microporous hollow carbon spheres for hydrogenation of CO2 to formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

Here, we report a general synthesis approach to produce PdAg nanoparticles (NPs) that are dispersed uniformly within N-doped microporous hollow carbon spheres (NMHCS) for hydrogenation of CO2 to formate. The optimized PdAg@NMHCS catalyst, which was obtained by using an optimized amount of…

Laccase production from sucrose by recombinant Yarrowia lipolytica and its application to decolorization of environmental pollutant dyes

Farshad Darvishi, Marzieh Moradi, Claude Jolivalt, Catherine Madzak

Laccases are used in decolorization and biodegradation of synthetic dyes, bioremediation of industrial waste-waters and delignification of lignocellulosic compounds. The aims of the present study were the optimization of a recombinant laccase production in Yarrowia lipolytica yeast using sucrose as…

Effect of the activation temperature on the state of gold supported on titania: An FT-IR spectroscopic study

Tz. Venkov, Katia Fajerwerg, L. Delannoy, Hr. Klimev, K. Hadjiivanov, C. Louis

The effect of the pre-treatment conditions on the evolution of gold species on an Au/TiO2 sample prepared by deposition–precipitation with urea has been followed by FT-IR spectroscopy of adsorbed CO. Gold is in the form of Au3+ species on the as-prepared sample and is not affected by evacuation at…

Synthesis and Unique Catalytic Performance of Single-Site Ti-Containing Hierarchical Macroporous Silica with Mesoporous Frameworks

Takashi Kamegawa, Norihiko Suzuki, Michel Che, Hiromi Yamashita

Single-site Ti-containing hierarchical macroporous silica with mesoporous frameworks (Ti-MMS) was successfully prepared by a solvent evaporation method using organic surfactant and poly(methyl methacrylate) (PMMA) colloidal crystals as the template. The formation of a well-defined macroporous…

High-Current-Density CO2-to-CO Electroreduction on Ag-Alloyed Zn Dendrites at Elevated Pressure

Sarah Lamaison, David Wakerley, Juliette Blanchard, David Montero, Gwenaelle Rousse, Dimitri Mercier, Philippe Marcus, Dario Taverna, Domitille Giaume, Victor Mougel, Marc Fontecave

High-surface-area Ag-Zn-alloyed electrodes undertake the rapid conversion of CO 2 to CO. This has the combined benefit of removing CO 2 and producing an industrially relevant chemical synthon. At atmospheric pressure, the electrodes plateau in activity owing to the mass-transport limitation of CO 2…

Formation of Activated Biomolecules by Condensation on Mineral Surfaces – A Comparison of Peptide Bond Formation and Phosphate Condensation

Thomas Georgelin, Maguy Jaber, Houssein Bazzi, Jean-François Lambert

Many studies have reported condensation reactions of prebiotic molecules, such as the formation of peptide bonds between amino acids, to occur to some degree on mineral surfaces. We have studied several such reactions on the same divided silica. When drying steps are applied, the equilibria of…

Pseudoaneurysm of anterior tibial artery following a diaphyseal fracture ă of the tibia mimicking a malignant bone tumor

Pierre Sautet, Elie Choufani, Philippe Petit, Franck Launay, Jean-Luc Jouve, Sebastien Pesenti

Pseudoaneurysms of the lower limb are rare and frequently iatrogenics ă complications. Closed traumas are likely to generate lesions of the ă arterial wall, which generally become symptomatic at a later stage. The ă diagnosis of such vascular lesion is difficult because the ă symptomatology and the…

Effect of Ca-doping on microstructure and photocatalytic activity of ZnO nanoparticles synthesized by sol gel method

R. Slama, J. El Ghoul, K. Omri, A. Houas, L. El Mir, Franck Launay

We report the synthesis of Zn1−xCaxO nanoparticles prepared by a sol–gel processing technique for x ranging from 0 to 0.05. The structural, morphological and optical properties of the nanoparticles were investigated by X-ray diffraction, transition electron microscopy, UV measurements, and…

Use of unconventional activation methods for the oxidative cleavage of lignin by dioxygen, Utilisation de moyens d’activation non-conventionnels pour le clivage oxydant de la lignine par le dioxygène

Louay Al-Hussaini

Due to the depletion of fossil resources, the interest of lignin as a sustainable alternative to petroleum is growing. Thus, the main purpose of this thesis was to develop a process for oxidative cleavage of lignin by dioxygen that involves unconventional methodologies like sonochemistry and ball-…, Du fait de l'épuisement des ressources fossiles, l'intérêt de la lignine en tant qu'alternative durable est grandissant. Ainsi, le but principal de cette thèse était de mettre au point un procédé de clivage oxydant de la lignine par le dioxygène qui implique des voies non…
