Lewis acido-basic interactions between CO2 and MgO surface: DFT and DRIFT approaches

Damien Cornu, Hazar Guesmi, Jean-Marc Krafft, Hélène Lauron-Pernot

Combined experimental infrared (IR) and theoretical approaches have been carried out in an attempt to specify the actual structure of the CO2 species adsorbed on the magnesium oxide surface. The interaction of CO2 with regular sites of the MgO(100), (111) and (110) surfaces as well as MgO(100)…

Importance, features and uses of metal oxide catalysts in heterogeneous catalysis

Jacques C. Védrine

This short review paper aims at assembling the present state of the art of the multiuses of metal oxides in heterogeneous catalysis, concerning liquid and gaseous phases of the reactant mixtures on solid catalysts. It includes the description of the main types of metal oxide catalysts, of their…

Controlling C−OAryl Hydrogenolysis vs Aryl Hydrogenation in Lignin Model Depolymerization Using Ni‐, Rh‐ or Ni/Rh‐based Silica Catalysts

Rita Raachini, Ferdaous Ben Romdhane, Capucine Sassoye, Maya Boutros, Franck Launay

Abstract This paper focuses on the hydrogenolysis of 2‐phenoxy‐1‐phenylethanone, modelling a pre‐oxidized form of lignin using five catalysts of similar metal content, prepared by impregnation of Ni(II), Rh(III) and both metals onto Aerosil‐380 in the presence of NH 3 , followed by a reduction step…

Electrochemistry of a new carbon-rich fluorine-doped tin oxide (CFTO) material as a powder electrode in chloride electrolytes

Chantal Cachet, Hubert Cachet, B Jousseaume, T Toupance, Vincent Vivier

The electrochemical behavior of a conductive carbon-rich fluorine-doped tin oxide (CFTO) powder synthesized via the sol–gel process was investigated by studying the chloride oxidation reaction in aqueous media with the help of a cavity microelectrode (CME) without any binding additive. This new…

Sulfamide chemistry applied to the functionalization of self-assembled monolayers on gold surfaces

Loïc Pantaine, Vincent Humblot, Vincent Coeffard, Anne Vallée

Aniline-terminated self-assembled monolayers (SAMs) on gold surfaces have successfully reacted with ArSO 2 NHOSO 2 Ar (Ar = 4-MeC 6 H 4 or 4-FC 6 H 4) resulting in monolayers with sulfamide moieties and different end groups. Moreover, the sulfamide groups on the SAMs can be hydrolyzed showing the…

Steam reforming of alpha-methylnaphthalene as a model tar compound over olivine and olivine supported nickel

Rudy Michel, Agata Lamacz, Andrzej Krzton, Gérald Djéga-Mariadassou, Philippe Burg, Claire Courson, Rene Gruber

At high temperature, biomass steam gasification generates tars and more particularly Polycyclic Aromatic Hydrocarbons (PAHs). To assess the ability of olivine-based catalyst to eliminate the tars by steam reforming, alpha-methylnaphthalene (MNP) was chosen as model compound. The Ni/olivine has…

Kinetic Model of Energy Transfer Processes Between Low-Coordinated Ions on MgO by Photoluminescence Decay Measurements

Céline Chizallet, Guylène Costentin, Jean-Marc Krafft, Hélène Pernot, Michel Che

Photoluminescence decay studies of emitting species on MgO nanocubes at room temperature provide evidence of three sur- face species characterized by an excitation and emission wave- length couple {l exc ;l em }.Species A corresponds to {l exc =240 nm; l em =380 nm},whereas the couple {l exc =280…

Plastic waste recycling via pyrolysis: A bibliometric survey and literature review

Sabino Armenise, Wong Syieluing, José M Ramírez-Velásquez, Franck Launay, Daniel Wuebben, Norzita Ngadi, Joaquín Rams, Marta Muñoz

Plastic materials have been crucial to the development of science, technology, and almost all aspects of modern progress since the mid-twentieth century. However, the increasingly unsustainable culture of plastic consumption and the accumulation of plastics in landfills, oceans, and broader…

Caracterización in-operando de catalizadores Fe-N-C para la reducción del H2O2 mediante microscopía electroquímica de barrido

Carlos M Sánchez-Sánchez, Christian Candia-Onfray, Ricardo Venegas, Lin Zhang, Sophie Juillard, Ricardo Salazar, José F. Marco, Nieves Menendez, Francisco Javier Recio, Vincent Vivier

Se han desarrollado diferentes rutas sintéticas para obtener catalizadores pirolizados Fe-N-C muy activos para la reacción de reducción de oxígeno (ORR). En particular, presentamos aquí las bases nitrogenadas del ADN y el ARN como precursores de C-N [1]. El H2O2 formado como subproducto durante la…

Supramolecular chiral self-assemblies of Gly–Pro dipeptides on metallic fcc(110) surfaces

C. Methivier, H. Cruguel, C.-M. Pradier, V. Humblot

Adsorption of the Glycine-Proline (Gly-Pro) dipeptide has been investigated using surface science complementary techniques on Au(110) and Ag(110), showing some interesting differences both in the chemical form and surface organization of the adsorbed peptide. On Au(110), Gly-Pro mainly adsorbs in…
