Function of Lattice Defects toward Photocatalytic Processes: View of Electronic Driven Force

Figure 3

(a) Pseudospace-filling model of ideal bulk-terminated (110) with a bridging oxygen vacancy. Blue (red) spheres are oxygen (titanium) atoms. (b) STM image of (1 × 1) (110) surface. The bright rows correspond to surface sites (red ball in (a)). Black row is bridging oxygen (Ob) and Ob-vacs are marked as the bright protrusions in the black row [43]. (c) Redistribution of the surface electronic density caused by single oxygen vacancy [64].
