Evidence for an H2 promoting effect in the selective catalytic reduction of NO(x) by propene on Au/Al2O3.

Tesnim Chaieb, Laurent Delannoy, Sandra Casale, Catherine Louis, Cyril Thomas

This work provides the first experimental evidence of an H2 effect in C3H6-SCR over an Au/Al2O3 catalyst. This effect could only be observed when the number of Au catalytic sites was decreased. The N2 turnover rate estimated for the first time for the Au catalytic sites for H2–C3H6-SCR was found to…

Surface immobilization mechanisms of cobalt ions on hydroxyapatite catalyst supports

Corentin Reynaud, Cyril Thomas, Dalil Brouri, Yannick Millot, Antoine Miche, Guylène Costentin

Cobalt deposition in an excess of solution was used to design Co-modified hydroxyapatite materials with various Co loadings and controlled dispersion. It is rationalized how the properties of hydroxyapatite supports (more or less stoichiometric compositions, nanorod or platelet morphologies and…

Ionic liquid route for the corrosion inhibition of Al alloys: the effect of butylammonium nitrate on the corrosion of AA2024-T6

Abdelmoheiman Zakaria Benbouzid, Oumaïma Gharbi, Najet Sidi-Yakoub, Mai T T Tran, Mireille Turmine, Vincent Vivier

In this work, the effect of an ammonium nitrate ionic liquid on the corrosion susceptibility of an Al-Cu-Mg alloy was investigated. The effect of the nitrate anion and the ammonium cation on the anodic and cathodic kinetics were studied separately using potentiodynamic polarisation testing,…

Role of Water on the Activity of Magnesium Silicate for Transesterification Reactions

Longfei Lin, Damien Cornu, Maya Mounir daou, Cyril Domingos, Virginie Herledan, Jean-Marc Krafft, Guillaume Laugel, Yannick Millot, Hélène Lauron-Pernot

This study aims to reveal how water adsorbed on to a solid can influence its catalytic properties for transesterification in liquid phase. A commercial magnesium silicate was subjected to a range of thermal pretreatments and used for the transesterification of ethyl acetate with methanol.…
