Spatially Controlled Reduction and Growth of Silver in Hollow Gold Nanoshell Particles

Lu Zhang, Peng Chen, Alexis Loiseau, Dalil Brouri, Sandra Casale, Michèle Salmain, Souhir Boujday, Bo Liedberg

Spatially controlled reactions at the nanoscale have attracted increasing interest for fundamental chemistry and for the engineering of novel functional materials. Herein, we demonstrate that pH-triggered reduction of silver ions preferentially occurs at the inner walls of porous and citrate-capped…

Heterometallic and Hydrophobic Metal–Organic Frameworks as Durable Photocatalysts for Boosting Hydrogen Peroxide Production in a Two-Phase System

Xiaolang Chen, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

Reductive production of hydrogen peroxide (H2O2) from dioxygen (O2) coupled with the oxidative synthesis of value-added products using hydrophobic metal–organic frameworks (MOFs) is very important for energy production. Herein, a hydrophobic iron-doped zirconium-based MOF (OPA/Fe-Zr-MOF), in which…

Pd–Cu Alloy Nanoparticles Confined within Mesoporous Hollow Carbon Spheres for the Hydrogenation of CO 2 to Formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

It is intriguing yet challenging to synthesize high-performance heterogeneous catalysts for carbon dioxide (CO2) hydrogenation reactions. The excellent catalytic performance of heterogeneous catalysts has attracted widespread attention recently. Herein, a series of Pd–Cu alloy nanoparticles…

Detection of hydrogen peroxide using dioxazaborocanes: elucidation of the sensing mechanism at the molecular level by NMR and XPS measurements

Thomas Caron, Pascal Palmas, Céline Frénois, Christophe Méthivier, Eric Pasquinet, Claire-Marie Pradier, Françoise Serein-Spirau, Lionel Hairault, Pierre Montméat

A fluorescent dioxazaborocane was synthesised and characterized, in order to study its turn-off sensing process for hydrogen peroxide detection. The exposure of the dioxazaborocane to diluted vapours of H2O2 led to a strong non reversible quenching of the fluorescence. Both NMR and XPS analyses…

PET waste as organic linker source for the sustainable preparation of MOF-derived methane dry reforming catalysts

Leila Karam, Arianna Miglio, Stefania Specchia, Nissrine El Hassan, Pascale Massiani, Julien Reboul

A catalyst made of Ni 0 nanoparticles highly dispersed on a lamellar alumina support was prepared by an environmentally-friendly route. The latter involved the synthesis of an aluminum-containing metalorganic framework (MOF) MIL-53(Al) in which the linkers were derived from the depolymerization of…

Plastic waste recycling via pyrolysis: A bibliometric survey and literature review

Sabino Armenise, Wong Syieluing, José M Ramírez-Velásquez, Franck Launay, Daniel Wuebben, Norzita Ngadi, Joaquín Rams, Marta Muñoz

Plastic materials have been crucial to the development of science, technology, and almost all aspects of modern progress since the mid-twentieth century. However, the increasingly unsustainable culture of plastic consumption and the accumulation of plastics in landfills, oceans, and broader…

Influence of the nature and environment of manganese in Mn-BEA zeolites on NO conversion in selective catalytic reduction with ammonia

Rafal Baran, L. Valentin, J.-M. Krafft, T. Grzybek, P. Glatzel, Stanislaw Dzwigaj

Manganese-containing BEA zeolites, MnxSiBEA (x = 1–4 wt %) and Mn(I.E.)AlBEA, were prepared by a two-step postsynthesis method and a conventional wet ion-exchange, respectively, and applied as catalysts in the selective catalytic reduction of NO with ammonia (NH3-SCR). The physicochemical analysis…

Redox-Triggered Control of Cell Adhesion and Deadhesion on Poly(lysine)- g -poly(ethylene oxide) Adlayers

Louise Hespel, Julien Dupré de Baubigny, Pierre Lalanne, Simon de Beco, Mathieu Coppey, Catherine Villard, Vincent Humblot, Emmanuelle Marie, Christophe Tribet

Spontaneous adsorption of poly(lysine)-g-poly(ethyleneglycol) comb-like copolymers (PLL-g-PEG) is a versatile mean to coat substrates with polymer layers that resist cell adhesion. We prepared redox cleavable PLL-g-PEG to switch adhesion on demand. Redox sensitivity was obtained by introducing…

Synthesis of RNA nucleotides in plausible prebiotic conditions from ab initio computer simulations

Andrea Pérez-Villa, Antonino Marco Saitta, Thomas Georgelin, Jean-François Lambert, François Guyot, Marie-Christine Maurel, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-d-ribose-1-diphosphate (α-PRPP) and nucleobases.…
