摘要
Using a combination of surface X-ray diffraction and mass spectrometry at realistic pressures, the CO oxidation reactivity of a Rh(111) model catalyst has been studied in conjunction with the surface structure. The measurements show that it specific thin surface oxide is always present in the high activity regime of Rh-based CO oxidation.
