Structural Reversibility and Nickel Particle stability in Lanthanum Iron Nickel Perovskite-Type Catalysts

Davide Ferri, Oliver Kröcher, Debora Foppiano, Andre Heel

Perovskite-type oxides have shown the ability to reversibly segregate precious metals from their structure. This reversible segregation behavior was explored for a commonly used catalyst metal, Ni, to prevent Ni sintering, which is observed on most catalys ...

Mode Coupling in Plasmonic Heterodimers Probed with Electron Energy Loss Spectroscopy

Jürgen Brugger, Olivier Martin, Duncan Thomas Lindsay Alexander, Jérémy Butet, Valentin Flauraud, Gabriel David Bernasconi

While plasmonic antennas composed of building blocks made of the same material have been thoroughly studied, recent investigations have highlighted the unique opportunities enabled by making compositionally asymmetric plasmonic systems. So far, mainly hete ...

Influence of defect distribution on the reducibility of CeO2-x nanoparticles

Maria Chiara Spadaro

Ceria nanoparticles (NPs) are fundamental in heterogeneous catalysis because of their ability to store or release oxygen depending on the ambient conditions. Their oxygen storage capacity is strictly related to the exposed planes, crystallinity, density an ...

Aqueous-phase hydrogenation of alkenes and arenes: The growing role of nano scale catalysts

Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Sviatlana Siankevich, Safak Bulut

In this article we highlight some of the recent developments in the aqueous-phase hydrogenation of alkenes and arenes. The traditional types of water-soluble catalysts applied in aqueous media are outlined together with recent trends towards the developmen ...

Computational Design of Strain in Core-Shell Nanoparticles for Optimizing Catalytic Activity

William Curtin, Philip Arthur Moseley

Surface strains in core–shell nanoparticles modify catalytic activity. Here, a continuum-based strategy enables accurate surface-strain-based screening and design of core–shell systems using minimal input as a means to enhance catalytic activity. The appro ...

Shape-Dependence of Pd Nanocrystal Carburization during Acetylene Hydrogenation

Lioubov Kiwi, Fernando Cardenas Lizana, Rocio Micaela Crespo Quesada

This interdisciplinary work combines the use of shape- and size-defined Pd nanocrystals (cubes of 10 and 18 nm, and octahedra of 37 nm) with in situ techniques and DFT calculations to unravel the dynamic phenomena with respect to Pd reconstruction taking p ...

Aqueous stabilisation of carbon-encapsulated superparamagnetic alpha-iron nanoparticles for biomedical applications

Heinrich Hofmann, Marie-Gabrielle Chantal Brigitte Ollivier Beuzelin, Lionel André Maurizi, Sandra Caroline Galmarini, Géraldine Sylvie Coullerez

Carbon-based nanomaterials, such as carbon-encapsulated magnetic nanoparticles (CEMNP, core@shell), show a wide range of desirable properties for applications in the biomedical field (clinical MRI, hyperthermia), for energy production and storage (hydrogen ...

Sn surface-enriched Pt–Sn bimetallic nanoparticles as a selective and stable catalyst for propane dehydrogenation

David Lyndon Emsley, Lidong Li

A new one pot, surfactant-free, synthetic route based on the surface organometallic chemistry (SOMC) concept has been developed for the synthesis of Sn surface-enriched Pt-Sn nanoparticles. Bu3SnH selectively reacts with [Pt]-H formed in situ at the surfac ...

Dielectric properties of silver nanoparticles coated with silica shells of different thicknesses

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

Core/shell nanoparticles having metallic silver nanoparticle cores of similar to 38 nm in diameter and silica shells of different thicknesses ranging from similar to 3.6-20 nm were prepared. For the silica coating, a slightly modified Stober method was use ...
