Our research on strontium ruthenate surfaces shows how water dissociates and strips off one hydrogen atom upon adsorption. Although the hydrogen atom and the remaining OH group are physically separated, the pieces continue to interact through a weak hydrogen bond. This interaction leads to an interesting dynamic behavior, where the OH group circles the stripped off hydrogen atom. The result were published in Nature Materials.

Our “magnetite subgroup” around Gareth Parkinson and Roland Bliem, with the help of our guest Jessi van der Hoeven from Utrecht, could nicely show how a prototype catalytic reaction works. They find that CO oxidation on their model catalyst, tiny platinum clusters on magnetite, eats the oxygen from the magnetite support, and platinum helps to oxidize the support again. They could also investigate in detail what happens if hydrogen is oxidized with the help of the catalyst. These results provide the groundwork to improve catalysts and got published in Angewandte Chemie International Edition.

A team around Gareth Parkinson of the Surface Physics group has solved a long-standing mystery: No one could explain why the magnetite Fe3O4(001) surface behaves differently than all other oxides. It turned out that this surface has a very peculiar crystal structure, which requires a new way of thinking about oxide surfaces in general. The results have been published in the prestigious journal Science.

Excess electrons in TiO
2 anatase are usually delocalized and behave as quasi-free particles. They are trapped, however, at defects such as steps. This is undesired in applications where a high electrical conductivity is essential, such as the Graetzel cell. On the other hand, electron localization can be beneficial in chemical applications. For example, oxygen prefers to adsorb close to surface steps. These effects are clearly seen in
STM and NC-AFM images taken by Martin Setvin and other members of the surface physics group. The experimental results have been confirmed in theoretical calculations by Xianfeng Hao, Cesare Franchini, and Geoerg Kresse from
Computational Materials Physics, University of Vienna.
The results were published in the journal Angewandte Chemie International Edition.

The SrTiO
3(110) surface forms a reconstruction that consists of a monolayer TiO
2, but in a special, rather unreactive - tetrahedrally coordinated - form. When oxygen vacancies are created in this layer, they move to the SrTiO
3 interface, where the resulting excess electrons form a two-dimensional gas (2DEG). Zhiming Wang, Stefan Gerhold and Bernhard Stöger from the surface physics group have measured the electronic structure of this electron gas at the synchrotron
Bessy in Berlin. (There they also took the happy photo at the right.) Different from other, known 2DEG's, this system shows a pronounced anisotropy that is depends on the doping level. The experimental results are complemented by theoretical calculations by Zhicheng Zhong and Karsten Held at the
Institute of Solid State Physics, and Xianfeng Hao and Cesare Franchini,
Computational Materials Physics, University of Vienna.
The results were published in the Proceedings of the National Academy of Sciences.

Anatase, a form of titanium dioxide (TiO2) is used in (photo)catalysis and many other applications. The interaction of oxygen molecules with this material is of central importance. How this happens on the atomic scale was investigated in experiments by Martin Setvin of the Surface Physics group and calculations by Annabella Selloni (Princeton University) and coworkers. It was found that O2 interacts with oxygen vacancies in the material, resulting in O2 (peroxo) molecules incorporated in the surface.
These results were published in the prestigious journal Science.

Metals such as gold or palladium are often used as catalysts to speed up certain chemical reactions. When the atoms ball together, most of them do not get into contact with the surrounding gas any more and the catalytic effect diminishes drastically. The mechanism of clustering is not well understood, however. In an article published in the prestigious journal Nature Materials, Gareth Parkinson and co-workers report on a detailed study of this issue; they have followed the fate of each surface atom and analyze how they are affected by different gas atmospheres. They find carbon monoxide to bind strongly to palladium atoms, helping them to move across the surface.
