H2O-Improved O2activation on the Pd-Au bimetallic surface.
Improved activation of adsorbed O2by co-adsorbed H2O on the Pd-Au(111) surface has been observed. When co-adsorbed with H2O, O2admolecules on the Pd-Au surface are more strongly bound via their interactions with H2O. This interaction leads to large enhancements in the dissociation of O2as determined via the generation of CO2upon exposure to CO.
