Abstract Despite tremendous importance in catalysis, the design of oxide-metal interface has been hampered by limited understanding nature interfacial sites and interaction (OMI). Through construction well-defined Cu 2 O/Pt, O/Ag O/Au interfaces, we find that O nanostructures (NSs) on Pt exhibit much lower thermal stability than Ag Au, although they show same structure.
