Hydrodenitrogenation of indole over Mo2C catalyst: Insights into mechanistic events through DFT modeling

Witold Piskorz, Grzegorz Adamski, Andrzej Kotarba, Zbigniew Sojka, Céline Sayag, G. Djéga-Mariadassou

The molecular reaction mechanism of hydrodenitrogenation of indole was studied using density-functional theory calculations of the adsorbed o-ethylaniline surrounded by mobile hydrogen atoms. It was found that the hydrogenation of o-ethylaniline occurs through two steps: consisting in…

Mesoporous silica supported amine and amine-copper complex for CO2 adsorption: Detailed reaction mechanism of hydrophilic character and CO2 retention

Bouhadjar Boukoussa, Aboubakr Hakiki, Nabil Bouazizi, Ana-Paola Beltrao-Nunes, Franck Launay, Alain Pailleret, Françoise Pillier, Abdelkader Bengueddach, Rachida Hamacha, Abdelkrim Azzouz

Mesoporous silica SBA-15 was functionalized with various amines and then doped with copper II cation (Cu2+). The modified materials were tested for the retention of CO2 at room temperature using temperature-programmed desorption (CO2-TPD). Several parameters affecting the CO2 retention capacity (…

On the use of a constant phase element (CPE) in electrochemistry

Samantha Michelle Gateman, Oumaïma Gharbi, Hercílio Gomes De Melo, Kieu Ngo, Mirelle Turmine, Vincent Vivier

Several techniques can be used to experimentally determine the interfacial capacitance of an electrode, which is a crucial parameter used for quantifying the efficiency of supercapacitors. However, the values obtained from cyclic voltammetry can be significantly different from those extracted from…

Acidity versus metal-induced Lewis acidity in zeolites for Friedel–Crafts acylation

Claire Bernardon, Manel Ben Osman, Guillaume Laugel, Benoît Louis, Patrick Pale

Acid catalysts including Ni, Ag and Fe-loaded zeolites of different structures were prepared either via cationic exchange or impregnation techniques from pristine H-zeolites (BEA, and MFI). Their catalytic activity was evaluated in the liquid-phase Friedel–Crafts acylation of anisole with propanoic…, Des cations métalliques (Ni, Ag et Fe) ont été incorporés au sein de zéolithes BEA et ZSM-5 par des techniques d'échange cationique et d'imprégnation afin d'obtenir de nouveaux catalyseurs acides solides. Ces matériaux ont ensuite été testés dans une réaction d'acylation de…
