Corundum-type metal oxide surfaces are ubiquitous. Most of their properties, e.g., their reactivity, proton conductivity and charge, strongly depend on reaction with water. However, understanding how water and oxides interact is challenging: it requires the description of processes that occur over many orders of magnitude in time and space. Here we address this multi-scale challenge both experimentally, by time averaged and ultrafast time resolved surface-sensitive vibrational spectroscopy, and theoretically, by quantum chemistry and molecular dynamics, for two corundum-type oxides, α-Al2O3 and α-Fe2O3, that are isostructural but differ dramatically in bulk electronic structure.
