Photoresponse of Visible Light Active CM-n-TiO2, HM-n-TiO2, CM-n-Fe2O3, and CM-p-WO3 towards Water Splitting Reaction
Figure 3
Partial geometry of the models for (a) one substitutional C atom to O (CS-O), (b) one substitutional C atom to Ti (CS-Ti), (c) one interstitial C atom (CI), and (d) one interstitial C atom nearby an oxygen vacancy (CI+VO) in the rutile supercell. The yellow spheres represent O atoms, the small brown spheres represent Ti atoms, and the black sphere presents the carbon impurity [68].
