EPR Characterization and Reactivity of Surface-Localized Inorganic Radicals and Radical Ions

Mario Chiesa, Elio Giamello, Michel Che

A review. The role of surface inorg. radicals and radical ions formed at the interface between a solid and a gas phase was discussed. The formation of such species is relevant to field such as electrochem., heterogeneous catalysts, photocatalysis and corrosion. The characterization of these…

Laboratory simulation to support the search for organic molecules at the surface of Mars

Olivier Poch, Cyril Szopa, Patrice Coll, Maguy Jaber, Thomas Georgelin, Jean-Francois Lambert, Fabien Stalport

The search for organic carbon at the surface of Mars, as clues of past habitability or remnants of life, is a major science goal of Mars’ exploration. Understanding the chemical evolution of organic molecules under current Martian environmental conditions is essential to support the analyses…

Effect of Cs impregnation on the properties of platinum in Pt/Na-BEA and Pt/Cs-BEA catalysts

Pascale Massiani, E.R. Silva, F.R. Ribeiro, M.F. Ribeiro, J.M. Silva

The presence of alkali cations in zeolite framework provides peculiar basic properties that influence the characteristics and reactivity of supported metal particles. Particularly, the addition of increasing amounts of cesium in Pt/Na-BEA and Pt/Cs-BEA catalysts, by CsOH impregnation, leads to…

Room-Temperature Synthesis of Iron-Doped Anatase TiO2 for Lithium-Ion Batteries and Photocatalysis

Christian Andriamiadamanana, C. Laberty-Robert, Moulay Tahar Sougrati, Sandra Casale, Carine Davoisne, Snehangshu Patra, Frédéric Sauvage

Iron-doped nanocrystalline particles of anatase TiO2 have been successfully synthesized using a complete room-temperature synthetic approach, leading to particles of high surface area (280 m2/g) and a narrowed band gap of 2.3 eV. These particles were introduced for photocatalysis under white light…

Zn-Cu Alloy Nanofoams as Efficient Catalysts for the Reduction of CO 2 to Syngas Mixtures with a Potential-Independent H 2 /CO Ratio

Sarah Lamaison, David Wakerley, David Montero, Gwenaëlle Rousse, Dario Taverna, Domitille Giaume, Dimitri Mercier, Juliette Blanchard, Huan Ngoc Tran, Marc Fontecave, Marc Mougel

Alloying strategies are commonly used to design electrocatalysts that take on properties of their constituent elements. Herein, we explore the use of such a strategy to develop Zn-Cu alloyed electrodes with unique hierarchical porosity and tunable selectivity for CO2 vs. H + reduction. By varying…
