Mapping amine functions at nanosurfaces using colloidal gold conjugation

Nicolas Debons, Dounia Dems, Christophe Méthivier, Christophe Calers, Antoine Miche, Thibaud Coradin, Carole Aimé

The functionalization of the surface of nanomaterials is a key approach to improve their stability, tune their reactivity and confer them specific properties. However, the mapping of functional groups at the nanometer scale remains difficult to achieve. This concerns not only the chemical nature of…

Physical techniques and catalyst preparation: Determining the interactions of transition-metal complexes with oxide surfaces

Xavier Carrier, Eric Marceau, Michel Che

This contribution presents the molecular approach used to investigate the different preparation steps of important catalytic systems, based on Mo, Ni, and Co. The first preparation step consists of impregnating oxide supports by aqueous solutions of transition-metal complexes (TMCs), called…

Thermodynamic brønsted basicity of clean MgO surfaces determined by their deprotonation ability: Role of Mg2+–O2 pairs

Céline Chizallet, Marie Laurence Bailly, Guylène Costentin, Hélène Lauron-Pernot, Jean Marc Krafft, Philippe Bazin, Jacques Saussey, Michel Che

The deprotonation ability of clean (i.e., carbonate- and hydroxyl-free) MgO surfaces of various morphologies towards protic molecules, such as propyne and methanol, is evaluated by following the adsorption modes and amount of dissociated species by FTIR. Photoluminescence is used to identify the…

1H MAS NMR study of the coordination of hydroxyl groups generated upon adsorption of H2O and CD3OH on clean MgO surfaces

Céline Chizallet, Guylène Costentin, Hélène Lauron-Pernot, Jocelyne Maquet, Michel Che

The coordination of OH groups on MgO has been characterized by 1H MAS NMR after appropriate pre-treatment conditions to obtain surfaces free from carbonates and with a controlled degree of hydroxylation. On MgO-sol–gel sample treated at 1023 K under flowing nitrogen, hydroxylated with water and…
