Heterolytic Splitting of H2 and CH4 on γ-Alumina as a Structural Probe for Defect Sites
Jérôme Joubert,Alain Salameh,V. Krakoviack,Françoise Delbecq,Philippe Sautet,Christophe Coperet,Jean-Marie Basset +6 more
TL;DR: In this article, a combined use of DFT periodic calculations and spectroscopic studies (IR and solid-state NMR) showed that a γ-alumina treated at 500 °C under high vacuum contains surface defects, which are very reactive toward H2 or CH4.

Synthesis, Characterization, and Catalytic Properties of γ-Al2O3-Supported Zirconium Hydrides through a Combined Use of Surface Organometallic Chemistry and Periodic Calculations
Jérôme Joubert,Françoise Delbecq,Chloé Thieuleux,Mostafa Taoufik,Frédéric Blanc,Christophe Coperet,Jean Thivolle-Cazat,Jean-Marie Basset, ,‡ and,Philippe Sautet +8 more
TL;DR: The treatment of the alumina-supported [Zr(CH2tBu)4], where Al stands for surface aluminum atoms, by H2 yields a mixture of aluminasupported zirconium hydride species, [(AlsO)2Zr (H)(μ-H)AlVI], along with cationic [Al IV-H]-+ in the vicinity of anionic tetrahedral aluminum hydrides [AlIV-H-] according to mass balance analysis, reactivity studies, IR spectroscopy, and periodic calculations RE

Alkane metathesis by a tungsten carbyne complex grafted on gamma alumina: Is there a direct chemical role of the support?
TL;DR: In this paper, the authors examined the case of a perhydrocarbyl tungsten complex grafted on gamma alumina from periodic density functional theory calculations and showed that hydration defects on the alumina surface can be active in alkane dehydrogenation toward alkenes.

Understanding the Selectivity in Hydrogenation of α,β-Unsaturated Aldehydes: A Water-Assisted Mechanism
Jérôme Joubert,Françoise Delbecq +1 more
TL;DR: In this article, the authors investigated the mechanisms of the competitive CC and CO hydrogenations of α,β-unsaturated aldehydes by means of calculations based on density functional theory.
