Comparison of fabrication methods for microstructured deep UV multimode waveguides based on fused silica

Autor: Patrick Sonström, Myriam Kaiser, Roman Priester, Martin Schreivogel, Marc Schmid, Michael Kneissl, Philipp Elmlinger

Publikováno v: Micro-Optics 2016.

The suitability of materials for deep ultraviolet (DUV) waveguides concerning transmittance, fabrication, and coupling properties is investigated and a fused silica core/ambient air cladding waveguide system is presented. This high refractive index c

Heterogeneous catalysis with supported platinum colloids: A systematic study of the interplay between support and functional ligands

Autor: Volkmar Zielasek, Xinwei Wang, Darius Arndt, Marcus Bäumer, Karsten Thiel, Jörg Stöver, Holger Borchert, Katharina Al-Shamery, Patrick Sonström

Publikováno v: Journal of Catalysis. 278:143-152

Whereas colloidal metal nanoparticles have attracted considerable interest in homogeneous catalysis, the effect of organic ligands has been less systematically investigated in heterogeneous gas-phase catalysis. This paper aims at elucidating this asp

Colloidally Prepared Pt Nanowires versus Impregnated Pt Nanoparticles: Comparison of Adsorption and Reaction Properties

Autor: Johannes Bernardi, Daniela Fenske, Patrick Sonström, Katharina Al-Shamery, Karin Föttinger, Sabine Schwarz, Andreas Haghofer, Günther Rupprechter, Marcus Bäumer

Publikováno v: Langmuir. 26:16330-16338

Ligand-capped Pt nanowires, prepared by colloidal synthesis and deposited on a high surface area γ-Al(2)O(3) support, were subjected to surface characterization by electron microscopy and FTIR spectroscopy using CO as a probe molecule. The structura

Colloidal Nanoparticles Embedded in Ceramers: Toward Structurally Designed Catalysts

Autor: Patrick Sonström, Xinwei Wang, Georg Grathwohl, Michaela Wilhelm, Michael Adam, Marcus Bäumer

Publikováno v: The Journal of Physical Chemistry C. 114:14224-14232

Ceramers constitute a new type of porous hybrid ceramic which is obtained by pyrolysis of polysiloxane precursors with organic side groups at temperatures low enough that part of the polymer has not yet been decomposed (≈500 °C). By using differen

Nanostructured Praseodymium Oxide: Correlation Between Phase Transitions and Catalytic Activity

Autor: Laura Schilinsky, Knut Müller, Patrick Sonström, Peter Behrend, Marcus Bäumer, Johannes Birkenstock, Andreas Rosenauer, Katharina Gries, Yulia Borchert

Publikováno v: ChemCatChem. 2:694-704

Praseodymia gives rise to a rich phase diagram with a large number of phases between the limiting stoichiometries Pr 2 O 3 and PrO 2 that differ only slightly in oxygen content (Pr n O 2n-2 ). This chemical and crystallographic variability allows the

Colloidally Prepared Pt Nanoparticles for Heterogeneous Gas-Phase Catalysis: Influence of Ligand Shell and Catalyst Loading on CO Oxidation Activity

Autor: Jörg Stöver, Holger Borchert, Jürgen Parisi, Katharina Al-Shamery, Joanna Kolny-Olesiak, Daniela Fenske, Patrick Sonström, Marcus Bäumer, Xiaodong Wang

Publikováno v: ChemCatChem. 2:198-205

In contrast to conventional methods, colloidally prepared heterogeneous supported metal catalysts are excellent systems to study the catalytic properties as a function of metal loading, monodispersity, particle shape, or the type of support without c
