Influence of synthesis parameters of mesocellular silica foams doped by nickel on methane reforming by CO 2

M. Boutros, O. Daoura, Franck Launay, P. Massiani, N. El Hassan

New catalysts based on Ni(0) dispersed onto mesocellular silica foams (MCF) were prepared for Dry Reforming of Methane (DRM). Different synthesis methods of MCF supports (with and without using NH4F or n-butanol) were tested in order to study the influence of the textural properties of the support…

Cellulose fibers modification through metal-free click chemistry for the elaboration of versatile functional surfaces

Alex Meye Biyogo, Louise Hespel, Vincent Humblot, Laurent Lebrun, François Estour

In the present work, a novel and versatile way was developed to functionalize cellulose fibers from wipes under heterogeneous conditions. The technic was based on metal-free click chemistry to avoid the persistence of any metal traces on cellulose. First, cellulose fibers were covalently pre…

Protic Ionic Liquids as Electrolytes for Metal-Hydride batteries

Ekaterina Kurchavova, Julie Chan, Junxian Zhang, Fermin Cuevas, Mickaël Mateos, Judith Monnier, Vincent Vivier, Mireille Turmine

Nowadays, the most popular and effective energy storage systems are Li-ion batteries, despite some limitations such as high cost, flammability, temperature restrictions, and use of critical raw material (e.g. Co) [1]. This raises the challenge of the demand for alternative systems. One potential…

Magnesium Hydroxide Methoxide Nanostructures for Catalytic Aldol Condensation Reactions

Jonathan Sierra-Cantor, Frédéric Richard, Bakytzhan Yeskendir, Claudia Sa, Jean-Dominique Comparot, Thomas Onfroy, Guillaume Laugel, Hélène Lauron-Pernot, Stéphane Celerier

The valorization of biomass into high-value chemicals via heterogeneous catalysis is a critical step toward sustainable chemical production. While acid catalysis has been extensively explored, basic catalysis remains underdeveloped due to challenges such as catalyst instability and energy-intensive…

Antimicrobial peptides (AMPs) are promising candidates for the development of future antibiotics. In an attempt to increase the efficacy of therapeutic AMPs, computer-based design methods appear as a reliable strategy. In this study, we evaluated the antimicrobial efficiency and mechanism of action…

The state of BEA zeolite supported nickel catalysts in CO2 methanation reaction

Wojciech Gac, Witold Zawadzki, Grzegorz Słowik, Marcin Kuśmierz, Stanislaw Dzwigaj

Two model nickel catalysts for CO2 methanation reaction were prepared by the impregnation method using unmodified and dealuminated BEA-type zeolite supports, denoted NiHAlBEA and NiSiBEA. Transmission electron microscopy (TEM) and X-ray diffraction studies evidenced formation of metallic nickel…

Unraveling the Direct Decomposition of NO x over Keggin Heteropolyacids and Their Deactivation Using a Combination of Gas-IR/MS and In Situ DRIFT Spectroscopy

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Cyril Thomas

Keggin heteropolyacids (HPAs) have been known to be efficient NOx absorbers for many years, and to decompose a significant fraction of the NOx species pre-absorbed at 100-150 °C into harmless N2 and O2 upon rapid heating to 450 °C. However, this capability of Keggin HPAs to directly decompose NOx…
