dc.description.abstract	(Figure Presented) The interaction of O2 with gold foil and gold nanoparticles grown by thermal deposition on TiO2(110) was studied by in situ ambient pressure X-ray photoelectron spectroscopy at room temperature. No spontaneous dissociation of O2 was observed either on Au foil or on Au nanoparticles up to 1 Torr of O2. X-ray irradiation, however, is very effective in promoting gold oxidation on both surfaces in the presence of O2. Our results help reconcile recent conflicting experimental observations regarding the activation of molecular oxygen, which is a crucial issue in Au catalyzed oxidation reactions.	es
