Interaction of Molecular Oxygen with the Vacuum Annealed TiO2 (110) Surface: Molecular and Dissociative Channels

Abstract

We have examined the interaction of molecular oxygen with the TiO2 (110) surface using temperature programmed desorption (TPD), isotopic labeling studies, sticking probability measurements and electron energy loss spectroscopy (ELS). Based on the variety of oxygen adsorption states observed in this study, further work is needed in order to determine which oxygen-related species play important roles in chemical photochemical oxidtion processes on TiO2 surfaces.
