Figure 7. (A) Experimental and simulated 1D 17O MAS NMR spectra of TiO2 (001). The simulated spectra are based on DFT calculations on different structures; (B) The structure model of TiO2 (101); (C) Experimental and simulated 1D 17O MAS NMR spectra of the fully dried surface-selectively 17O-labeled TiO2 (101) (black line). The simulated spectra (colored lines and peaks) by using parameters obtained from DFT calculations. Reproduced with permission from[105].
