XPS spectra of a B 1s for TiO2-xBx and PtSA/NP-TiO2-xBx. b Pt 4f for PtSA/NP-TiO2 and PtSA/NP-TiO2-xBx. c normalized Ti K-edge XANES spectra of TiO2, TiO2-xBx and reference Ti foil and TiB2. d normalized Pt L3-edge XANES spectra and e FT-EXAFS spectra of PtSA/NP-TiO2-xBx and reference Pt foil and PtO2. f Pt L3-edge fitted EXAFS spectra of R space for PtSA/NP-TiO2-xBx. g WT EXAFS contour plots for the k3-weighted Pt L3-edge EXAFS of Pt foil, PtO2 and PtSA/NP-TiO2-xBx. R denotes the radial distance (Å) and k denotes the photoelectron wave vector (Å−1) in XAFS analysis. Source data are provided as a Source Data file.
