Synthesis and Catalytic Properties of Nanoparticulate Intermetallic Ga–Pd Compounds
Autor: Marc Armbrüster, Matthias Friedrich, Gregor Wowsnick, Marc Heggen, Raul Cardoso-Gil
Publikováno v: Journal of the American Chemical Society. 133:9112-9118
A two-step synthesis for the preparation of single-phase and nanoparticulate GaPd and GaPd(2) by coreduction of ionic metal-precursors with LiHBEt(3) in THF without additional stabilizers is described. The coreduction leads initially to the formation

Autor: Robert Schlögl, Matthias Friedrich, Youngmi Yi, Michael Hävecker, Manfred Erwin Schuster, Gregor Wowsnick, Klaus Hermann, Zailai Xie, Rosa Arrigo, Axel Knop-Gericke, Patrick Kast, Lili Sun
Publikováno v: ACS Catalysis
In this work, the geometric and electronic structure of N species in N-doped carbon nanotubes (NCNTs) is derived by X-ray photoemission (XPS) and absorption spectroscopy (NEXAFS) of the N 1s core excitation. Substitutional N species in pyridine-like

Surface dynamics of the intermetallic catalyst Pd2Ga, Part I – Structural stability in UHV and different gas atmospheres
Autor: Yuri Grin, Gregor Wowsnick, Aiping Zhang, Frank Girgsdies, Robert Schlögl, Malte Behrens, Marc Armbrüster, Igor Kasatkin, Detre Teschner
Publikováno v: Journal of Catalysis
The structural and electronic properties of unsupported Pd2Ga were investigated after different pre-treatments. Pd2Ga provides with respect to elemental Pd a significantly modified electronic structure with its d-band center being shifted away from t

Surface dynamics of the intermetallic catalyst Pd2Ga, Part II : Reactivity and stability in liquid-phase hydrogenation of phenylacetylene
Autor: Gregor Wowsnick, Frank Girgsdies, Robert Schlögl, Igor Kasatkin, Yuri Grin, Detre Teschner, Marc Armbrüster, Malte Behrens
Publikováno v: Journal of Catalysis
The catalytic properties of unsupported Pd 2 Ga for the liquid-phase hydrogenation of phenylacetylene are investigated after different pre-treatments with focus on the stability of the catalyst during reaction. The surface of as-prepared Pd 2 Ga cons

In situ study of catalytic processes: neutron diffraction of a methanol synthesis catalyst at industrially relevant pressure
Autor: Robert Schlögl, Igor Kasatkin, Thomas C. Hansen, Timur Kandemir, Edward L. Kunkes, Gregor Wowsnick, Frank Girgsdies, Malte Behrens, Nikolas Jacobsen, Klaus-Dieter Liss
Publikováno v: Angewandte Chemie International Edition
Studying the workplace: An industrial methanol synthesis catalyst operating at high pressure was studied by in situ neutron diffraction. The peculiar microstructure of Cu/ZnO/Al2O3 nanocatalysts was found to be stable under reaction conditions. Stack
