Halide Ligands to Release Strain in Cadmium Chalcogenide Nanoplatelets and Achieve High Brightness

Marion Dufour, Junling Qu, Charlie Gréboval, Christophe Méthivier, Emmanuel Lhuillier, Sandrine Ithurria

Zinc blende II-VI semiconductor nanoplatelets (NPLs) are defined at the atomic scale along the thickness of the nanoparticle and are initially capped with carboxylates on the top and bottom [001] facets. These ligands are exchanged on CdSe NPLs with halides that act as X-L-type ligands. These CdSe…

Two-Dimensional Layers of Colloidal CdTe Quantum Dots: Assembly, Optical Properties, and Vibroelectronic Coupling

Thomas Noblet, Souhir Boujday, Christophe Methivier, Marie Erard, Julie Hottechamps, Bertrand Busson, Christophe Humbert

The manufacturing of silica platforms functionalized by CdTe quantum dots (QDs) of 3.4 nm diameter through (3-aminopropy)triethoxysilane (APTES) aliphatic organosilanes is performed to preserve QDs excitonic properties after their transfer from colloidal solutions to surfaces at ambient air. In…

Covalent Transition Metal Borosilicides: Reaction Pathways in Molten Salts for Water Oxidation Electrocatalysis

Daniel Janisch, Fernando Igoa Saldaña, Edouard de Rolland Dalon, Carlos V. M. Inocêncio, Yang Song, Pierre-Olivier Autran, Antoine Miche, Sandra Casale, David Portehault

The properties of transition metal borides and silicides are intimately linked to the covalent character of the chemical bonds within their crystal structures. Bringing boron and silicon together within metal borosilicides can then engender different competing covalent networks and complex charge…

Transition metal borides of Ni-B (Co-B) as alternative non-precious catalytic materials: Advances, potentials, and challenges. Short review

Marek Lewandowski, Maria Bartoszewicz, Karolina Jaroszewska, Gérald Djéga-Mariadassou

This review gives a brief presentation of the types, structure, synthesis, and application of amorphous transition metal borides (Mt-B) in particular the bulk or supported nickel and cobalt borides (NiB and CoB). Mt-B materials are amorphous metal-metalloid alloys and constitute an important group…

Comparing the mechanism of urea and ammonia electro-oxidation reactions on Ni-based catalysts

Sophia Akkari, Carlos M Sánchez-Sánchez, Vincent Vivier

In recent decades, special attention has been paid to the electrochemical oxidation of organic compounds, such as urea (H2NCONH2) from urine, in order to avoid their natural degradation into detrimental products, as well as to produce energy by using fuel cells [1]. Its presence in sewages and its…

Integrated stopped-flow device for the study of porous materials using hyperpolarized $^{129}$Xe NMR

Jing Li, Estelle Léonce, Corentin Coutellier, Céline Boutin, Kévin Chighine, Charles Rivron, Anne Davidson, Patrick Berthault

A simple, low-cost, and efficient device is proposed for the study of porous materials via NMR using small gas probes. Mainly built through additive manufacturing and being equipped with a radiofrequency solenoid microcoil, it only requires tiny quantities of sample and/or gas and is particularly…

Probing Acid Base Properties in Group V Aluminum Containing Zeolites

A. Wojtaszek, Maria Ziolek, Frederik Tielens

The stability and acid base properties of group V Al containing zeolites have been investigated using a combination of experiment and theory. Using periodic density functional theory for a systematic investigation on a series of model zeolites, it is shown that the XdO group is more stabilized for…

Platinum-zeolite hybrid catalyst for the electrooxidation of formic acid

Lu Zhang, Juan V Perales-Rondón, Angélica Thomère, Juliette Blanchard, Carlos M Sánchez-Sánchez

Formic acid oxidation reaction (FAOR) was studied using different platinum-zeolites hybrid catalysts. The catalysts were prepared by addition of two different forms of the ZSM-5 zeolite (ZSM-5-H+ and ZSM-5-NH4+) to an ink containing Vulcan carbon support and Pt nanoparticles (NPs). TEM images…
