Also for the interface (ii) site we find a similar trend for the restructured Ru nanorod as for the original structure up to the 2VO system, with a continuous up-shift of the d-band (see Figure , right and Table ). Like for the interface (i) site, re-structuring up-shifts the d-band center by about 0.2 eV compared to the systems in the original structure. Comparing with the CO adsorption energy, the continuous slight increase from 0VO to 1VO, followed by a significant increase to the 2VO system, is at best qualitatively reproduced by the more continuous shift of the d-band center. Going to the 3V and 5VO systems, we find distinct differences in the trend of the d-band center between restructured and non-restructured systems.
