Phosphoribosyl Pyrophosphate: A Molecular Vestige of the Origin of Life on Minerals

Mariame Akouche, Maguy Jaber, Marie-Christine Maurel, Jean-François Lambert, Thomas Georgelin

In this contribution, we report the formation under prebiotic conditions of phosphoribosyl pyrophosphate (PRPP) as a molecular precursor in the one-pot synthesis of a canonical nucleotide, namely adenosine monophosphate (AMP) from its building blocks (KH2PO4 or Pi, adenine, and d-ribose), on a…

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…

Copper incorporated mesoporous materials: synthesis, characterization and catalytic activity in benzaldehyde reduction

O. Zekri, A. Saadi, F. Launay, C. Calers, C. Rabia

Copper substituted mesoporous silica materials (Cu–HMS-n), with a variety of Si/Cu atomic ratios (n) ranging from 50 to 100, were synthesized by the one-pot sol–gel method using dodecylamine as template. These materials were characterized by X-ray diffraction, N2 adsorption-desorption, transmission…

Unlocking synergy in bimetallic catalysts by core–shell design

Jessi van der Hoeven, Jelena Jelic, Liselotte Olthof, Giorgio Totarella, Relinde van Dijk-Moes, Jean-Marc Krafft, Catherine Louis, Felix Studt, Alfons van Blaaderen, Petra de Jongh

Extending the toolbox from mono- to bimetallic catalysts is key in realizing efficient chemical processes1. Traditionally, the performance of bimetallic catalysts featuring one active and one selective metal is optimized by varying the metal composition1,2,3, often resulting in a compromise between…
