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…

Sustainable production of acrolein: effects of reaction variables, modifiers doping and ZrO2 origin on the performance of WO3/ZrO2 catalyst for the gas-phase dehydration of glycerol

Song-Hai Chai, Li-Zhi Tao, Bo Yan, Jacques C. Vedrine, Bo-Qing Xu

Zirconia-supported tungsten oxide (WO3/ZrO2 or WZ) is known as an efficient catalyst for selective acrolein (AC) production from gas-phase dehydration of glycerol (GL). Two catalysts (WZ-CP and WZ-AN) were prepared herein using, respectively, a ZrO(OH)2 hydrogel (ZrO(OH)2-CP) and its derived…

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…

Discrimination of infrared fingerprints of bulk and surface POH and OH of hydroxyapatites

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Souhir Boujday, Guylene Costentin

The identification of the nature of the surface acid base pairs present on hydroxyapatites surface is a key point to rationalize their catalytic properties. To investigate the possible involvement of acidic protonated phosphate (POH) and/or of basic OH emerging from the channels, the spectroscopic…

Gold Nanoparticles Assembly on Silicon and Gold Surfaces: Mechanism, Stability and Efficiency in Diclofenac Biosensing

Maroua Ben Haddada, Maria Hübner, Sandra Casale, Dietmar Knopp, Reinhard Niessner, Michele Salmain, Souhir Boujday

We investigated the assembly of Gold nanoparticles (AuNPs) on Gold and Silicon sensors with two final objectives: (i) understanding the factors governing the interaction and (ii) building up a nanostructured piezoelectric immunosensor for diclofenac, a small-sized pharmaceutical pollutant.…

Nanostructured and spiky gold in biomolecule detection: improving binding efficiencies and enhancing optical signals

E. E. Bedford, S. Boujday, C.-M. Pradier, F. X. Gu

Nanostructured gold can improve the ability to detect biomolecules. Whether planar nanostructured surfaces or nanostructured particles are used, similar principles governing the enhancement apply. The two main benefits of nanostructured gold are improved geometry and enhancement of optical…

Non-thermal plasma assisted catalytic NOx remediation from a lean model exhaust

Olivier Gorce, Hervé Jurado, Cyril Thomas, Gérald Dega-Mariadassou, Ahmed Khacef, Jean Marie Cormier, Jean Michel Pouvesle, Gérard Blanchard, Sabine Calvo, Yvanne Lendresse

No efficient catalyst presently exists for deNOx in lean burn conditions. Furthermore, actual catalysts generally deactivate during reaction. A cylindrical DBD non-thermal plasma reactor was coupled with a stable three-function catalyst in order to verify the nature of the effect of the plasma on…
