Extended Data Figure 4: XANES characterization of Pt/α-MoC.
From: Low-temperature hydrogen production from water and methanol using Pt/α-MoC catalysts
a, Platinum L3-edge and b, molybdenum K-edge XANES results from fresh and used 0.2%Pt/α-MoC. These XANES spectra suggest that charge transfer from platinum to molybdenum is unchanged after the reaction, and that there is no sign of bulk phase oxidation in α-MoC. c, Pt L3-edge XANES spectra of Pt/α-MoC catalysts with different Pt loadings. Platinum foil and platinum oxide were used as standards. The position of the ‘white line’ (dashed line) shows gradual positive movement (from 0.5 eV to 0.6 eV) with decreasing Pt loading.
