Formation energy for C-related defects in anatase Ti16O32 (a) O-poor limit ΔμO = −4.1 eV and ΔμC = 0 eV. (b) O-rich limit ΔμO = 0 eV and ΔμC = −4.07 eV. (c) O-intermediate (Experimental growth condition) ΔμO = −1.5 eV. (d) Phase diagram for C-related defects (C)O, (CO)O, (C2)O. The region within the rectangular red lines represents the experimentally relevant conditions at T = 848 K with a realistic \({p}_{{{\rm{O}}}_{2}}\) range.
