An EPR characterisation of stable and transient reactive oxygen species formed under radiative and non-radiative conditions

E. Richards, D. M Murphy, M. Che

Electron paramagnetic resonance (EPR) spectroscopy is the ideal method of choice when detecting and studying the wide variety of paramagnetic oxygen-centred radicals. For simple diatomic radicals, such as the superoxide (O 2 −) or peroxy (ROO •) species, the CW EPR profile (in particular the g-…

2D Monolayer of 1T' Phase of Alloyed WSSe from Colloidal Synthesis

Ashkan Shahmanesh, Davide Romanin, Corentin Dabard, Sang-Soo Chee, Charlie Gréboval, Christophe Methivier, Mathieu G Silly, Julien Chaste, Matthieu Bugnet, Debora Pierucci, Abdelkarim Ouerghi, Matteo Calandra, Emmanuel Lhuillier, Benoit Mahler

We explore the colloidal growth of monolayers of WSSe alloy in their 1T' phase with various Se content. We develop a synthetic procedure leading to reduced aggregation of the flakes. The presence of a narrow band-gap close to the top of the valence band has been evidenced combining…

Introduction of Co into the Vacant T-Atom Sites of SiBEA Zeolite as Isolated Mononuclear Co Species

Rafal Baran, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A CoSiBEA zeolite was obtained by a postsynthesis method which consisted of a treatment of tetraethylammonium BEA zeolite with nitric acid in the first step and introduction of Co ions into the vacant T atom sites of the SiBEA zeolite by reaction of aqueous Co(NO3)2 solution with silanol groups.…

The similarities and differences in structural characteristics and physico-chemical properties of AgAlBEA and AgSiBEA zeolites

Stanislaw Dzwigaj, Nataliia Popovych, Pavlo Kyriienko, Jean-Marc Krafft, Sergiy Soloviev

AgAlBEA and AgSiBEA zeolites have been prepared by two preparation procedures. The conventional wet impregnation is used to obtain AgAlBEA with silver present mainly in extra-framework position. The two-step postsynthesis procedure which consists of first creating the vacant T-atom sites with…

Cu segregation in Au–Cu nanoparticles exposed to hydrogen atmospheric pressure: how is fcc symmetry maintained?

Q. Wang, A. Nassereddine, D. Loffreda, C. Ricolleau, D. Alloyeau, C. Louis, L. Delannoy, J. Nelayah, H. Guesmi

In a recent work [A. Nassereddine et al., Small 2021, 17, 2104571] we reported the atomic-scale structure and dynamics of sub-4 nm sized Au nanoparticles (NPs) supported on titania in H2 at atmospheric pressure obtained by using aberration-corrected environmental transmission electron microscopy (…

Control of stoichiometry, size and morphology of inorganic polymers by template assisted coordination chemistry

Pierrick Durand, Giulia Fornasieri, Cédric Baumier, Patricia Beaunier, Dominique Durand, Eric Rivière, Anne Bleuzen

Recent years have seen the discovery of fascinating electronic properties in Prussian blue analogues and derivatives making them appealing candidates for the realization of molecular devices. Their successful integration into real applications however depends on a further processing step allowing…

Ethylene production via catalytic dehydration of diluted bioethanol: a step towards an integrated biorefinery

Ilenia Rossetti, Matteo Compagnoni, Elisabetta Finocchio, Gianguido Ramis, Alessandro Di Michele, Yannick Millot, Stanislaw Dzwigaj

After a preliminary thermodynamic investigation, proper operating conditions have been selected to maximize ethylene productivity by ethanol dehydration and limit side products such as coke and higher olefins or oxygenates. We focused on the possibility to operate with a diluted bioethanol solution…
