Similar to O-vacancy formation aside the Ru nanorod, also in this case the Ru-induced lowering of the O-vacancy formation energy is less than expected from the linear correlation between Ru-induced lowering of the O-vacancy formation energy and the charge transfer from the support to the Ru nanorod derived in Figure (red line in Figure ). This is particularly evident for O-vacancy formation at the (iii) site. Again, the structural contribution is much higher, by about 1.0 eV, than in the other cases (marked by a red dashed rectangle in Figure , see also Table ), supporting again our suggestion that significant structural contributions to the O-vacancy formation energy generally result in more pronounced deviations from the linear correlation between the O-vacancy induced charge transfer to the Ru nanorod and the Ruinduced lowering of the O-vacancy formation energy.
