Petit Voyage vers la surface : Structure et réactivité de solides inorganiques, A small trip to the surface: structure and reactivity of inorganic solids

Lorenzo Stievano

Dans ma carrière, j'ai eu la chance et le privilège de m'attaquer à des problématiques scientifiques très variées, qui peuvent être ressemblées par le concept fédérateur de l'application de méthodes d'analyses physico-chimiques pour la compréhension de la structure et de la…

Stabilization of ribofuranose by a mineral surface

Thomas Georgelin, Maguy Jaber, Frederic Fournier, Guillaume Laurent, France Costa-Torro, Marie-Christine Maurel, Jean-François Lambert

The existence of the ribose moiety in biomolecules poses two problems for prebiotic chemistry. First, the exclusive presence of the furanose isomer in RNA has to be accounted for since furanose is a minor form in solution and does not exist in crystals. Second, all D-ribose polymorphs are unstable…

Selective Oxidation of Methane to Formaldehyde Catalyzed by Phosphates: Kinetic Description by Bond Strengths and Specific Total Acidities

Vasilij Gomonaj, Hervé Toulhoat

A kinetic model predicts the experimental activity and selectivity patterns obtained in oxidation of methane for divided unsupported orthophosphates (M II 3(PO4)2, M III PO4,) and pyrophosphates (M II 2P2O7, M IV P2O7) catalysts spanning extended ranges of M-O bond strength (calculated from first…

Gold/Polyoxometalate Core/Shell Nanoparticles for Combined Chemotherapy–Photothermal Cancer Therapy

Somia Tomane, Claire Wilhelm, Souhir Boujday, Alexandre Fromain, Antoine Miche, Flavien Bourdreux, Anne Dolbecq, Pierre Mialane, Anne Vallée

We designed monodisperse and perfectly shaped core/shell AuNP@Mo4Zol2Mn nanohybrids consisting of gold nanoparticles (AuNPs) functionalized by an antitumoral polyoxometalate (POM) incorporating the biologically active zoledronate ligand. After incubation, the nanoparticles were readily confined in…

Biomass-mediated ZSM-5 zeolite synthesis: when self-assembly allows to cross the Si / Al lower limit

Marcelo Maciel Pereira, Elisa Gomes, Alessandra Vieira Silva, Ana Belen Pinar, Marc-Georg Willinger, Sangaraju Shanmugam, Céline Chizallet, Guillaume Laugel, Pit Losch, Benoit Louis

A family of Al-rich ZSM-5 zeolites with Si / Al = 8 ± 0.5 was prepared according to a biomass-mediated supramolecular approach. A combination of advanced characterisation techniques and periodic density functional theory (DFT) calculations unraveled the purity and stability of unexpected Al-…

Prebiotic chemistry

J.F. Lambert, M. Sodupe, P. Ugliengo

Without doubt, one of the most fascinating questions ever asked is ''What is life?'', immediately followed by ''How and where did life arise?''. Both questions are by no means exclusively related to chemistry and biology. Indeed, it was soon realized that…

Study of gold electrodissolution by scanning electrochemical microscopy in different modes

Divino Salvador Ramírez-Rico, Michel Keddam, Erika Roxana Larios-Durán, Vincent Vivier

The electrodissolution of gold has already been widely studied by several methods, but no consensus concerning the reaction mechanism has been reached. In this work, the scanning electrochemical microscopy (SECM) has been used in transient condition for studying the electrodissolution of gold in…

Compared activity and stability of three Ni-silica catalysts for methane bi- and dry reforming

Karam Jabbour, M.N. Kaydouh, N El Hassan, H El Zakhem, Sandra Casale, Anne Davidson, Pascale Massiani

A low weight % of Ni (5 wt %) and the two solvents technique of deposition are used to obtain well-dispersed Ni-species (either particles or species dispersed on the silica surface) and avoid the formation of large particles on three silicas SBA-15, Aerosil 300 and diatoms MN3. Stability tests at…
