We have investigated hydroxylation and water adsorption on α Fe 2O3(0001) at water vapor pressures up to 2 Torr and temperatures ranging from 277 to 647 K (relative humidity (RH) < 34%) using ambient-pressure X-ray photoelectron spectroscopy (XPS).

We report the first measurements on the quantitative partitioning of water between its molecular and dissociated forms at a gas−metal interface under elevated water pressures and temperatures. By means of synchrotron-based in situ photoelectron spe

An interfactant for metal oxide heteroepitaxy: Growth of dispersed ZrO2(111) films on FeO(111) precovered Ru(0001)

We introduce an interfactant for zirconium oxide heteroepitaxy and propose that dispersed, epitaxial films of materials which are hard to crystallize are accessible by growing them on top of an ultrathin, polar FeO(111) film.

Potassium-Promoted Iron Oxide Model Catalyst Films for the Dehydrogenation of Ethylbenzene: An Example for Complex Model Systems

Autor: Wolfgang Ranke, Guido Ketteler, Robert Schlögl

Publikováno v: Journal of Catalysis

Details of the surface structure and composition of potassium-promoted iron oxide model catalyst films prepared on Ru(0001) are investigated by scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and Auger electron spectrosco

We report different wetting properties of Cu(110) and Cu(111) at near-ambient conditions using in situ photoemission spectroscopy. At near-ambient conditions of pressure (1 Torr) and temperature (295 K), the Cu(110) surface is covered with a mixed OH
