Figure 16. 2D 11B 3QZ-FAM MAS NMR spectra (sheared) of (A) 10% B-doped and (B) (B, Ag)-codoped TiO2 samples. 2D 11B DQ MAS NMR spectra of (C) 10% B-doped and (D) (B, Ag)-codoped TiO2 samples. Possible Boron Species in B-doped and (B, Ag)-codoped TiO2 were shown at the bottom. Reproduced with permission from[202].
