Improved activation of adsorbed O2 by co-adsorbed H2O on the Pd-Au(111) surface has been observed. When co-adsorbed with H2O, O2 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 O2 as determined via the generation of CO2 upon exposure to CO.
