Species migration across interfacial boundaries can affect the function of bimetallic catalysts. Here the authors report that palladium oxide drives the reduction of silver oxide by facilitating molecular hydrogen dissociation and migration of hydrogen atoms across the Pd–Ag interface with concurrent surface restructuring.
