Fig. 2

a Aberration-corrected high-angle annular dark-field (AC HADDF-STEM) image of Zn1-TiO2, the scale bar is 2 nm; this image is representative of at least three independent experiments with similar results; b 3D heatmap of the brightness of enlarged AC HAADF STEM image of Zn1-TiO2; c high-resolution Zn 2p XPS spectra of Zn1-TiO2; d high-resolution O1s XPS spectra of TiO2 and Zn1-TiO2; e Zn K-edge of near-edge XANES spectra for Zn1-TiO2 and Zn foil; f k3-weighted FT-EXAFS spectra; g FT EXAFS fitting curves of Zn K-edge; wavelet transform of the k3-weighted EXAFS contour plots of h Zn foil and i Zn1-TiO2.
