Determining the Behavior of RuOx Nanoparticles in Mixed-Metal Oxides: Structural and Catalytic Properties of RuO2/TiO2(110) Surfaces

Hot off the wire: Scanning tunneling microscopy, X‐ray photoelectron spectroscopy, and density functional calculations were used to study the interaction of RuO2 nanostructures with TiO2(110). Ruthenium oxide forms unique Ru3O6 wire‐like structures on TiO2 that can be easily reduced and re‐oxidized...

Summary:Hot off the wire: Scanning tunneling microscopy, X‐ray photoelectron spectroscopy, and density functional calculations were used to study the interaction of RuO2 nanostructures with TiO2(110). Ruthenium oxide forms unique Ru3O6 wire‐like structures on TiO2 that can be easily reduced and re‐oxidized at temperatures in the range of 400–600 K, and it has a very high catalytic activity for the low‐temperature oxidation of CO.
