Improved activation of adsorbed O-2 by co-adsorbed H2O on the Pd-Au(111) surface has been observed. When co-adsorbed with H2O, O-2 admolecules on the Pd-Au surface are more strongly bound via their interactions with H2O. This interaction leads to large enhancements in the dissociation of O-2 as determined via the generation of CO2 upon exposure to CO.
