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)…

Insight into the Nature of the ZnO x Promoter during Methanol Synthesis

Remco Dalebout, Laura Barberis, Giorgio Totarella, Savannah Turner, Camille La Fontaine, Frank de Groot, Xavier Carrier, Ad van der Eerden, Florian Meirer, Petra de Jongh

Despite the great commercial relevance of zinc-promoted copper catalysts for methanol synthesis, the nature of the Cu–ZnOx synergy and the nature of the active Zn-based promoter species under industrially relevant conditions are still a topic of vivid debate. Detailed characterization of the…

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…

Influence of the postsynthesis preparation procedure on catalytic behaviour of Ag-loaded BEA zeolites in the hydrodechlorination of 1,2-dichloroethane into value added products

A. Śrębowata, R. Baran, G. Słowik, D. Lisovytskiy, Stanislaw Dzwigaj

Two silver-containing BEA zeolites prepared by a two-step postsynthesis method (Ag2.0SiBEA) and a conventional wet impregnation (Ag2.0HAlBEA) showed a high activity in the conversion of 1,2-dichloroethane (1,2-DCE) into value added products with 100% selectivity into ethylene and 100% selectivity…

The impact of the hydrodechlorination process on the physicochemical properties of bimetallic Ag-CuBeta zeolite catalysts

A. Śrębowata, Izabela I. Kamińska, S. Casale, D. Brouri, C. Calers, Stanislaw Dzwigaj

Beta zeolites with two Si/Al ratios of 17 and 1300 were used for synthesis of Ag2.0Cu2.0HAlBeta and Ag2.0Cu2.0SiBeta zeolites by conventional wet impregnation and two-step postsynthesis methods, respectively. The calcination of Ag2.0Cu2.0HAlBeta and Ag2.0Cu2.0SiBeta at 773 K for 3 h in air led to…

Influence of preparation procedure on catalytic activity of PdBEA zeolites in aqueous phase hydrodechlorination of 1,1,2-trichloroethene

Izabela I. Kamińska, Dmytro Lisovytskiy, Sandra Casale, Anna Śrębowata, Stanislaw Dzwigaj

Pd-loaded BEA zeolites containing 1 wt % of Pd were prepared by a two-step postsynthesis method (PdSiBEA and PdSiAlBEA) and a conventional wet impregnation (PdHAlBEA). Modification of BEA zeolite resulted in the introduction of Pd ions into zeolite framework as pseudo-tetrahedral Pd(II) and extra-…

Enzymatic Approach in Calcium Phosphate Biomineralization: A Contribution to Reconcile the Physicochemical with the Physiological View

Clément Guibert, Jessem Landoulsi

Biomineralization is the process by which organisms produce hard inorganic matter from soft tissues with outstanding control of mineral deposition in time and space. For this purpose, organisms deploy a sophisticated “toolkit” that has resulted in significant evolutionary innovations, for which…

Tuning Surface Chirality of Adsorbed Gly-Pro Dipeptide/Cu(110) by Changing its Chemical Form via Electrospray Deposition.

Christophe Méthivier, Hervé Cruguel, Dominique Costa, Claire-Marie Pradier, Vincent Humblot

By changing the Ultra High Vacuum (UHV) deposition method, classical sublimation versus electrospray ionization, one can tune the chemistry of a chiral dipeptide molecule (Gly-Pro, GP), when adsorbed on a Cu(110) surface, from anionic to zwitterionic, respectively. This chemical shift will…
