Solvent effects in catalysis: rational improvements of catalysts via manipulation of solvent interactions

Paul Joseph Dyson, Philip Gregory Jessop

In homogeneous catalysis, the main emphasis on improving catalyst performance (rate, yield and selectivity) is directed towards manipulation of the ligands. The steric and electronic effects of ligands are extremely well understood and the rational design ...

Ruthenium Dispersion: A Key Parameter for the Stability of Supported Ruthenium Catalysts during Catalytic Supercritical Water Gasification

Christian Ludwig, Frédéric Vogel, Gaël Peng

The catalytic supercritical water gasification of isopropanol (450 degrees C, 30 MPa) over Ru catalysts supported on carbon and metal oxides was performed in a fixed-bed plug flow reactor. The Ru loading was between 1.2 and 2%. The catalyst stability over ...

Molecular Adsorption Changes the Quantum Structure of Oxide-Supported Gold Nanoparticles: Chemisorption versus Physisorption

Wolf-Dieter Schneider

STM conductance spectroscopy and mapping has been used to analyze the impact of molecular adsorption on the quantized electronic structure of individual metal nanoparticles. For this purpose, isophorone and CO2, as prototype molecules for physisorptive and ...

Spherical superstructures of oxide nanoparticles for catalytic reactions in microchemical reactors

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker

We report the fabrication of spherical superstructures composed of SiO2 and TiO2 nanoparticles and their applications in catalyzing organic reactions. Assembling of the nanoparticles into superstructures is done by heating a water-in-oil micro-emulsion, wh ...

Iron oxide nanoparticles supported on activated carbon fibers catalyze chemoselective reduction of nitroarenes under mild conditions

Lioubov Kiwi, Duncan Thomas Lindsay Alexander, Oliver Anthony Beswick

Highly dispersed iron oxide (Fe2O3) nanoparticles (NPs) have been immobilized on structured supports of activated carbon fibers (ACF). Systematic catalyst characterizations suggest that ACF-based catalysts remain ultra-microporous after Fe2O3 NPs (similar ...

Highly Selective Catalytic Reduction of Nitro- to Azoarenes under Ambient Conditions

Lioubov Kiwi, Carlos Gilberto Morales Guio

Catalytic system of Au nanoparticles supported on metal oxides has been developed to produce azoarenes in one-step directly from nitroarenes under mild conditions (30 °C, 1 bar of N2) using 2-propanol as solvent and reducing agent. Close to 100 % chemosele ...

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 ...

Chemical Aspects of Nanoparticle Ecotoxicology

Kristin Schirmer, Laura Sigg, Renata Behra, Hannah Inka Schug, Yang Yue

Nanoecotoxicology strives to understand the processes and mechanisms by which engineered nanoparticles (ENP) may exert toxic effects on aquatic organisms. Detailed knowledge of the chemical reactions of nanoparticles in the media and of their interactions ...
