Alkyne hydrogenation over Pd catalysts: A new paradigm

Autor: S. David Jackson, Attila Wootsch, Spiros Zafeiratos, Mounir Chamam, Detre Teschner, Michael Hävecker, James McGregor, Axel Knop-Gericke, Hermann Sauer, Peter Schnörch, Robert Schlögl, Arran S. Canning, Lynn F. Gladden, Elaine M. Vass, Jonathan J. Gamman

Publikováno v: Journal of Catalysis. 242:26-37

The hydrogenation of 1-pentyne over various palladium catalysts was studied under various conditions. In the regime of selective hydrogenation, as observed by in situ X-ray photoelectron spectroscopy, significant amounts of subsurface carbon and a Pd

Effect of hydrogen pressure on intentional deactivation of unsupported Pt catalyst: Catalytic properties and physical characterization

Autor: Zoltán Paál, Attila Wootsch, Hermann Sauer, Ute Wild, István Bakos, Robert Schlögl, Sándor Szabó

Publikováno v: Applied Catalysis A: General. 309:1-9

Unsupported Pt black reduced by hydrazine looked like an agglomeration of elongated Pt particles, as confirmed by electron microscopy. Cyclic voltammetry indicated the presence of low Miller-index (e.g. {1 0 0} and {1 1 1} facets) as well as terrace

Surface and structural properties of pt/ceo2catalyst under preferential co oxidation in hydrogen (PROX)

Autor: Detre Teschner, Hermann Sauer, Attila Wootsch, Robert Schlögl, Olga Pozdnyakova, Axel Knop-Gericke

Publikováno v: Reaction Kinetics and Catalysis Letters

Preferential oxidation of CO in the presence of excess hydrogen was studied on Pt/CeO2 with 5% metal loading. Catalytic data were similar to those observed on 1% Pt/CeO2 earlier [Wootsch et al. J. Catal. 225 (2004) 259]. The optimum temperature regio

Pt/ceria thin film model catalysts after high-temperature reduction: a (HR)TEM study

Autor: Simon Penner, Günther Rupprechter, Robert Schlögl, Hermann Sauer, Dang Sheng Su, Konrad Hayek, Richard Tessadri, Raimund Podloucky

Publikováno v: Vacuum

Well-facetted Pt particles, epitaxially grown on (001) NaCl single crystal surfaces, were supported by thin films of crystalline ceria. Structural and morphological changes due to calcination and reduction have been studied after treating in oxygen (

The effect of oxidation on the structure of nickel nanoparticles

Autor: Bernd Rellinghaus, Eberhard F. Wassermann, B. Spliethoff, Hermann Sauer, Sonja Stappert

Publikováno v: The European Physical Journal D. 16:249-252

The structural properties of nickel nanoparticles which are prepared by means of DC sputtering in argon and subsequently oxidized in ambient air are reported. Ex situ structural and chemical investigations utilizing (high resolution) transmission ele
