Synergy between unique Pt–C coordination and Pt quantum dots on TiO2 for exceptional photocatalytic methanol dehydrogenation
Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 2. Chemical characterization of the catalysts. (A) XANES spectra of Ti K-edge for TiO2, C/TiO2, and Pt–C/TiO2. (B) Pt L-edge of Pt–C/TiO2, PtO2, and Pt foil. (C) Fourier transform of k2-weighted EXAFS spectra at Pt L-edge of Pt–C/TiO2, PtO2, and Pt foil. (D) Normalized C K-edge of Pt–O/TiO2 (black curve) and Pt–C/TiO2 (red curve). (E) Normalized C K-edge of Pt–O/TiO2 (black curve) and Pt–C/TiO2 (red curve). (F) Normalized Ti L-edge of Pt–O/TiO2 (black curve) and Pt–C/TiO2 (red curve).
