About the role of oxide phases in the methanol oxidation over copper foil studied by in situ XAS

Michael Hävecker Axel Knop‐Gericke Thomas Schedel‐Niedrig Robert Schlögl

Since a long period the methanol oxidation over copper has been a topic of intensive investigations with various methods. Two main reaction paths occur: the total oxidation of methanol to CO2 and water and the partial oxidation to formaldehyde and hydrogen or water. An interesting point is the role of the oxygen in the catalytic reaction. From ex situ surface science studies it is concluded that oxygen can both act as a promoter and as an inhibitor of the reaction [1]. A big variety of oxygen species can occur at copper surfaces. Moreover one often has to face the problem that the structure of the catalyst can be significantly different under reaction condition from that observed after the reaction or ex situ. Therefore it is very helpful to perform a surface sensitive experiment during the reaction to get direct hints about the oxygen species present under these conditions. To draw conclusions about their function it is necessary to monitor simultaneously the conversion of the gas phase. Such an experiment is usually referred to as in situ. a) b)

Improved CuGaSe/sub 2/-based solar cell performance by In-S surface treatments

David Fuertes Marrón A. Meeder Sebastian Lehmann M. Rusu Thomas Schedel‐Niedrig

CuGaSe/sub 2/ (CGSe) thin films for photovoltaic applications have been subjected to surface treatments based on In-S by means of chemical vapor deposition. Structural and electronic characterization of as-grown films and processed devices show the effective incorporation of In and S in the near-surface region of CGSe thin films and a positive impact on the solar cell performance.

Hochdruck-Niederenergie-Röntgenabsorptionsspektroskopie: ein Beitrag zur Überwindung des „pressure gaps” in der Untersuchung heterogenkatalytischer Prozesse

Angewandte Chemie (1998)

Michael Hävecker Axel Knop‐Gericke Thomas Schedel‐Niedrig Robert Schlögl

Erstmals wurde unter Praxisbedingungen durch oberflächenempfindliche Röntgenabsorption im Bereich der weichen Röntgenstrahlung am Beispiel der Methanoloxidation an Kupfer eine aktive Oberflächenphase charakterisiert und ihre Funktion mit der katalytischen Aktivität des Systems korreliert. Es handelt sich bei dieser Phase nicht um an der Oberfläche adsorbierten Sauerstoff (linkes Bild, O = schwarze Kugeln), sondern um ein im oberflächennahen Bereich gebildetes Kupfersuboxid (rechtes Bild).

Catalytic Methanol Oxidation over Copper: Observation of Reaction-Induced Nanoscale Restructuring by Means of In Situ Time-Resolved X-ray Absorption Spectroscopy

Chemistry - A European Journal (2000)

Ingolf Böttger Thomas Schedel‐Niedrig Olaf Timpe Rainer Gottschall Michael Hävecker

The catalytically active copper phase for the partial oxidation of methanol is studied by means of time-resolved extended X-ray absorption fine structure (EXAFS) spectroscopy combined with the detection of the catalytic turnover. It is found that the active form of the copper is a strained nanocrystalline form of the metal. The metal is no longer made up from large crystallites but contains a defect structure in which oxygen is already intercalated. Die zeit-aufgelöste ausgedehnte Feinstruktur der Röntgenabsorptionskante (EXAFS) wurde zur Untersuchung der katalytisch aktiven Kupferphase bei der Partialoxidation von Methanol analysiert und mit Messungen des katalytischen Umsatzes kombiniert. Es konnte gezeigt werden, daß die aktive Kupferphase sich als eine verzerrte nanokristalline Form des Metall darstellen läßt, die nicht mehr aus großen Nanokristalliten aufgebaut ist, sondern eine Defektstruktur besitzt, in der Sauerstoff intercaliert ist.
