Understanding the stabilization mechanism of the Y- stabilized zirconia (YSZ) (100) surface has triggered a great debate over the past 30 years. In this work, we focused on a fundamental study on the surface structure of YSZ(100) by polarization-resolved infrared reflection absorption spectroscopy (IRRAS), in combination with grazing-emission X-ray photoelectron spectroscopy (XPS). The combined IR and XPS results allowed to gain detailed insight into the adsorption of carbon monoxide and carbon dioxide on YSZ(100) over a large coverage range from submonolayer to multilayers. The experimental data were further analyzed based on the density functional theory (DFT) calculations.
