On the radical cracking of n-propylbenzene to ethylbenzene or toluene over Sn/Al2O3-Cl catalysts under reforming conditions

S Toppi, C Thomas, C Sayag, D Brodzki, Katia Fajerwerg, F Lepeltier, C Travers, G Djegamariadassou

Two series of chlorided-alumina-supported Sn catalysts were synthesized with different precursors, SnCl2 or SnBu4, and with various contents of Sn. The acidity of the catalysts including 0.2 wt% Sn was characterized by FTIR adsorption–desorption of 2,6-dimethylpyridine (Brønsted acidity) and…

Ring-closure on the Rocks in a Prebiotic Environment

Louis M P Ter-Ovanessian, Marie-Christine Maurel, Jean-François Lambert

Ring-closure is a key step in current pyrimidine anabolism and one may wonder whether cyclisation reactions could be promoted in the geochemical context at the origins of life, i.e. with the help of minerals. Various prebiotic minerals were tested in this work, including silica, carbonates,…

Ni-exsolved catalysts from hard templated mesoporous LaNiO3 perovskite for highly efficient NH3 decomposition

Sebastian Gamez, Ferdaous Ben Romdhane, Josefine Schnee, Eric Gaigneaux

LaNiO3 perovskites have been recently studied for H2 production from NH3 decomposition / cracking. So far, this material has had its catalytic performance boosted along the addition of basic doping agents. Nevertheless, little attention has been paid to the potential benefit to gain from its…

Unravelling surface changes on Cu-Ni alloy upon immersion in aqueous media simulating catalytic activity of aerobic biofilms

Nesrine Aissaoui, Irma Liascukiene, Michel Genet, Christine Dupont-Gillain, Karim El Kirat, Caroline Richard, Jessem Landoulsi

Cu-Ni alloys are extensively used in contact with natural waters and are impacted by microbial activities of biofilms. The mechanisms by which surface changes occur upon immersion remain not well understood. Herein, an aerobic microbial activity of natural biofilms is mimicked by the enzymatic…

Embedding Collagen in Multilayers for Enzyme-Assisted Mineralization: A Promising Way to Direct Crystallization in Confinement

Elodie Colaço, Clément Guibert, Jihye Lee, Emmanuel Maisonhaute, Dalil Brouri, Christine Dupont-Gillain, Karim El Kirat, Sophie Demoustier-Champagne, Jessem Landoulsi

The biogenic calcium phosphate (CaP) crystallization is a process that offers elegant materials design strategies to achieve bioactive and biomechanical challenges. Indeed, many biomimetic approaches have been developed for this process in order to produce mineralized structures with controlled…

New Insights into Radical Mechanisms in Natural Drying Oils: Paint Binders as Reactors for Nanoparticle Formation

Laurence de Viguerie, Yongjie Yang, Fabrice Morlet-Savary, Jacques Lalevée, Sandra Casale, Christine Péchoux, Maguy Jaber, Gilles Patriarche

Understanding radical processes in drying oils is essential for both heritage science and materials chemistry, as these reactions govern film formation and long-term stability in historical paintings. In this study, we investigate radical mechanisms in linseed oil, a traditional paint binder. Gold…
